 was another source. It was probably farming populations, attentive to rain and temperature for their crops, that noticed the qualitative differences in winds – some were humid, others dry, some hot, others cold – and that these qualities depended on where the wind was blowing from. Local directional names were used to refer to the winds, eventually giving the wind itself a proper name

, irrespective of the observer's position. This was likely furthered by sailors who, far from landmarks at sea, nonetheless recognized a particular wind by its qualities and referred to it by a familiar name.

Kedem (East) is used frequently as the name of a scorching wind that blows from the east. There are several passages referring to the scattering of people "to all the winds".

Unlike the Biblical Israelites, the early Greeks maintained two separate and distinct systems of cardinal directions and winds, at least for a while.

The etymology of the names of the four archaic Greek winds is uncertain. Among tentative propositions is that Boreas might come from "boros", an old variant of "oros" (Greek

Another is that it comes from the phrase ὰπὸ της βoης ("from the roar"), a reference to its violent and loud noise. Notos probably comes from "notios" ("moist", a reference to the warm rains and storms brought from the south). Eurus and Zephyrus seem to come from "brightness" (q.v.Eos

. This refers to the fact that the "east" (sunrise) and "west" (sunset) are not stable on the horizon, but depend on the season, i.e. during the winter, the sun rises and sets a little further south than in the summer, Consequently, the Homeric system may have had six winds – Boreas (N) and Notos (S) on the meridian axis, and the other four on diagonals: Zephyrus (NW), Eurus (NE), Apeliotes (SE) and Argestes (SW).

Meteorology (Aristotle)
Meteorology is a treatise by Aristotle which contains his theories about the earth sciences. These include early accounts of water evaporation, weather phenomena, and earthquakes....

(c.340 BCE), introduced a ten-to-twelve wind system. One reading of his system is that there are eight principal winds: Aparctias (N), Caecias (NE), Apeliotes (E), Eurus (SE), Notos (S), Lips (SW), Zephyrus (W) and Argestes (NW). Aristotle then goes on to add two half-winds, Thrascias (NNW) and Meses (NNE), noting that they "have no contraries". Later, however, Aristotle suggests the Phoenicias wind for the SSE (blows locally in some places), but suggests nothing for SSW. So, seen this way, Aristotle really has an asymmetric windrose of ten winds, as two winds are effectively missing or only local.

North (N) Aparctias (ὰπαρκτίας)
(variant Boreas (βoρέας))
the top meridian
North-Northeast (NNE) Meses (μέσης) the polar "rise"
Northeast (NE) Caecias (καικίας) the summer sunrise
East (E) Apeliotes (ὰπηλιώτης) the equinox sunrise
Southeast (SE) Eurus (εΰρος)
(variant Euronoti (εὺρόνοtοi))
the winter sunrise
South-Southeast (SSE) No wind
(except local Phoenicias (φοινικίας)
South (S) Notos (νόtος) the bottom meridian.
South-Southwest (SSW) No wind
Southwest (SW) Lips (λίψ) the winter sunset
West (W) Zephyrus (ζέφυρος) the equinox sunset
Northwest (NW) Argestes (ὰργέστης)
(Variants: Olympias(όλυμπίας),
Sciron (σκίρων)
the summer sunset.
North-Northwest (NNW) Thrascias (θρασκίας) the polar "set"


Notice that in the Aristotelean system, old Eurus is shunted from its traditional position in the cardinal East by Apeliotes (ὰπηλιώτης), meaning "from the Sun" or from "the heat of the Sun".

 (in Aristotle's day, Thrace covered a larger area than today, including the north-northwest of Greece). Finally, Meses (μέσης) might simply mean "middle", presumably because it was a half-wind.

The implication of reading Thrascias and Meses as half-winds, and the others as principal winds, is that this implies Aristotle's construction is asymmetric. Specifically, the half-winds would be at 22½° on either side of the North, while the principal eight would be at 45° angles from each other. However, an alternative hypothesis is that they will be more equally spaced around 30° from each other.

, it has been calculated that this construction would yield a symmetric compass rose with approximately 30° angles all around.

If set out on a compass card, Aristotle's system could be conceived of as a twelve-wind rose with four cardinal winds (N, E, S, W), four "solsticial winds" (loosely speaking, NW, NE, SE, SW), two "polar winds" (roughly NNW, NNE) and two "non-winds" (SSW, SSE).

Aristotle explicitly groups Aparctias (N) and the half-winds Thrascias (NNW) and Meses (NNE) together as "north winds" and Argestes (NW) and Zephyrus (W) together as "west winds" — but he goes on to note that both the north and west winds could be classified as "generally northerly" (Boreae), since they all tend to be cold. Similarly Lips (SW) and Notos (S) are "south winds" and Eurus (SE) and Apeliotes (E) are "east winds", but once again, both south and east winds are "generally southerly" (Notiae) because are all relatively warm (Aristotle reasons that as the sun rises in the east, then it heats east winds longer than west winds). With this general classification, Aristotle manages to account for the archaic Greek two-wind system.

The exception to this system is Caecias (NE), which Aristotle notes is "half north and half east", and thus neither generally northern nor generally southern. The local Phoenicias (SSE), is also designated as "half south and half east".

Aristotle goes on to discuss the meteorological properties of the winds, e.g. that the winds on the NW-SE axis are generally dry, while the NE-SW winds are wet (NE producing heavier clouds than SW). N and NNE bring snow. Winds from the whole northwestern sector (NW, NNW, N) are described as cold, strong, cloud-clearing winds that can bring lightning and hurricanes with them. Aristotle also makes special note of the periodic bending summer Etesian

 winds, which comes from different directions depending on where the observer lives.

Aristotle had aggrandized the wind system beyond Homer to ten winds, but he left it unbalanced. It would be left to subsequent geographers to either add two more winds (to SSW and SSE) to make it into a symmetric 12-wind compass (as Timosthenes

 (c.282 BCE) had developed a system of 12 winds by adding four winds to the eight. (Agathemerus is, of course, incorrect – Aristotle had at least ten winds, not eight).

Timosthenes's list (according to Agathemerus) was Aparctias (N), Boreas (not Meses, NNE), Caecias (NE), Apeliotes (E), Eurus (SE), "Phoenicias is also called Euronotos" (SSE), Notos (S), "Leuconotos alias Libonotos" (first mention, SSW), Lips (SW), Zephyrus (W), Argestes (NW) and "Thrascias alias Circius" (NNW).
In many ways, Timosthenes marks a significant step in the evolution of the compass rose. Depending on how Ventorum Situs is dated, Timosthenes can be credited with turning Aristotle's asymmetric ten-wind compass into to a symmetric twelve-wind compass, by introducing the SSW wind (Leuconotos/Libonotos) omitted by Aristotle and Theophrastus and assigning the compound "Euronotos" (already alluded to by Aristotle, no mention of Theophrastus's Orthonotos here) in place of the local Phoenicias (SSE). His highlighting of the Italian "Circius" as a major variant of Thrascias (NNW) could be the first indication of the notorious Mistral

 wind of the west Mediterranean. Another major change in Timoesthenes is that he shunts Boreas out of the North position and into NNE (replacing Meses) – which will become customary in later authors.

Timosthenes is also significant for being perhaps the first Greek to go beyond treating these "winds" merely as meteorological phenomena and to begin viewing them properly as points of geographic direction.

The differences of De Mundo from Timosthenes are that (1) it introduces Libophoenix as another name for Libonotos (Leuconotos not mentioned); (2) two alternates to Argestes are mentioned – Iapyx (as in the Ventorum) and Olympias (as in Aristotle) (Timosthenes mentions no variants for this wind), (3) like Aristotle, De Mundo refers to a collective of north winds, the Boreae.

Eratosthenes and the Tower of Winds

It is said that the geographer Eratosthenes
Eratosthenes
Eratosthenes of Cyrene was a Greek mathematician, poet, athlete, geographer, astronomer, and music theorist.He was the first person to use the word "geography" and invented the discipline of geography as we understand it...

 of Cyrene (c.200 BCE), realizing that many winds presented only slight variations, reduced twelve winds down to eight principal winds. Eratosthenes's own work has been lost, but the story is reported by Vitruvius
Vitruvius
Marcus Vitruvius Pollio was a Roman writer, architect and engineer, active in the 1st century BC. He is best known as the author of the multi-volume work De Architectura ....

, who goes on to say Eratosthenes came to this conclusion in the course of measuring the circumference of the earth, and felt there were really only eight equally sized sectors, and that other winds were but local variations of these eight principal winds. If true, that would make Eratosthenes the inventor of the eight-wind compass rose

.

It is worth nothing that Eratosthenes was a disciple of Timosthenes and is said to have drawn principally from his work. But it is interesting to note how they part ways on this. Both recognized that Aristotle's ten-wind rose was unbalanced, but while Timosthenes restored balance by adding two winds to make it a symmetric twelve, Eratosthenes deducted two wind to make it a symmetric eight.

It seems that, in practical appeal, Eratosthenes's reduction may have won the day. The famous "Tower of the Winds

Pliny

Pliny the Elder
Pliny the Elder
Gaius Plinius Secundus , better known as Pliny the Elder, was a Roman author, naturalist, and natural philosopher, as well as naval and army commander of the early Roman Empire, and personal friend of the emperor Vespasian...

 in his Natural History (C.77 CE) after noting that twelve was an exaggeration, goes on to note that the "moderns" have reduced it to eight. He lists them as Septentrio (N), Aquilo (NNE), Subsolanus (E), Vulturnus (SE), Auster (S), Africus (SW), Favonius (W) and Corus (NW).

Notice that Caecias (NE) is not part of this octet. Instead, Pliny puts the half-wind Aquilo (NNE) there instead. It seems Pliny is aware Aquilo is a half-wind, because since he says it lies "in between Septentrio and the summer sunrise" (although in a later chapter he places it at the summer sunrise). If the first version is taken, this means Pliny's eight-wind compass is asymmetric. Pliny goes on to mention that Aquilo is also "named Aparctias and Boreas" (the Boreas identification with NNE is already in Timosthenes, but Aparctias's demotion from the N is novel).

When he goes on to discuss half-winds, Pliny re-introduces Caecis as lying "between Aquilo and Subsolanus", thus restoring it effectively to its NE position. Evidently reading Aristotle, Pliny tries to insert long-lost Meses again "between Boreas (= Aquilo) and Caecis", thus placing Meses in a position that (in a modern 32-point compass) would be called "Northeast by north". Confusing matters, in a later chapter, Pliny goes on to say that Aquilo, in the summer, turns into the Etesian

 winds, the periodic wind already referred to by Aristotle. Pliny also mentions, for the other half-winds, Phoenicias (for SSE, not Euronotus), Libonotus (SSW), and Thrascias (NNW).

It is apparent Pliny had recently read Aristotle and sought to resurrect some of the abandoned Aristotelean names (Boreas/Aparctias, Meses, Etesian winds, Phoenicias, he even mentions Olympias and Sciron as local Greek winds), albeit they appear rather awkwardly when inserted into the contemporary 12-wind compass schema.

, possibly inspired by the Tower of the Winds in that city, reduces the Latin rose to from twelve to eight winds, the principal winds, for which he gives both the Latin and Greek terms. He lists them as:
  • N – Septentrio (Latin), Aparctias (Greek)
  • NE – Aquilo (Latin), Boreas (Greek)
  • E – Eurus (Latin), Apeliotes (Greek), Subsolanus ("to Roman sailors")
  • SE – Vulturnus (Latin), Euronotus (Greek)
  • S – Auster (Latin), Notos (Greek)
  • SW – Africus (Latin), Lips (Greek)
  • W – Favonius (Latin), Zephyrus (Greek)
  • NW – Caurus (Latin), Argestes (Greek)


Among the novelties is the disappearance of Caecias (NE, like in Pliny), although he does make a later note that "Caecias" is mentioned in Aristotle (but does not give it a position). Aquilo/Boreas seem well-enthroned at NE. Another surprise is the re-emergence of Eurus in the East, where it has not been seen since Homer. He seems to treat Eurus as a Latin name, giving the Aristotelean Apeliotes as the Greek equivalent, and reducing Subsolanus to a mere variant "from Roman sailors". With Eurus now absent in the SE, Euronotus (previously SSE) is promoted to the vacant SE position. Finally, a new name, Caurus, is introduced as the NW wind. This is almost certainly a misspelling of Corus (NW).

Aulus Gellius gives some information about local winds. He mentions Circius as a local wind in Gaul
Gaul

. Divided into twelve equal sides, on each of its sides, it has inscribed the names of the classical winds, both in Greek and in Latin. The Vatican table lists them as follows:
Wind Latin inscription Greek inscription Greek read as: Notes
N Septentrio AΠAPKIAC Aparkias (ὰπαρκίας) Greek misspelling.
NNE Aquilo BOPEAC Boreas (βoρέας) as in Timosthenes
NE Vulturnus KAIKIAC Caecias (καικίας) Vulturnus (normally SE) is in wrong place.
This should be 'Caecias'.
E Solanus AΦHAIωTNS Apheliotes (ὰφηλιώτης) Greek misspelling.
New Latin name (normally Subsolanus).
SE Eurus EYPOC Eurus (εΰρος) New Latin name. Vulturnus should be here.
SSE Euroauster EYPONOTOC Euronotos (εὺρόνοtος)) New Latin name (normally Euronotus)
S Auster NOTOC Notos (νόtος)
SSW Austroafricus AIBONOTOC Libonotos (λιβόνοtος) New Latin name (normally, Libonotus)
SW Africus AIΨ Lips (λίψ)
W Favonius ZEΦYPOC Zephyrus (ζέφυρος)
NW Chorus IAΠYZ Iapyx (ιαπίξ) Latin name misspelled (normally Corus)
NNW Circius ΘPAKIAC Thrakias (θρακίας) Greek misspelled,
New Latin name (normally Thrascias),
from Timosthenes

There are several spelling mistakes, both in Greek (Aparkias, Apheliotes, Thrakias) and Latin (Chorus with an h, Solanus minus Sub). The principle error of the Vatican table is the misplacement of Vulturnus in NE rather than SE, with the result that the old Greek Eurus now resumes its place in Latin. This error will be repeated later. There is also a significant new Latin name, Austroafricus, in place of Libonotus, and Circius in place of Thrascias (although the latter was already anticipated by Timosthenes). The old "Iapyx" (of the Venturum Situs) also makes a comeback (in Greek).

Isidore of Seville

Etymologiae is an encyclopedia compiled by Isidore of Seville towards the end of his life. It forms a bridge between a condensed epitome of classical learning at the close of Late Antiquity and the inheritance received, in large part through Isidore's work, by the early Middle Ages...

(c.620 CE). In the chapter on winds, Isidore provided a list practically identical to that of the marble Roman amenoscope held at the Vatican. Isidore also tried to supply the etymology of each of the terms:
  • Septentrio (N) – Isidore correctly relates it to the Arctic circle

    ). Septentrio means "commander of the seven", and the Pole Star

    The term "Pole Star" usually refers to Polaris, which is the current northern pole star, also known as the North Star.In general, however, a pole star is a visible star, especially a prominent one, that is approximately aligned with the Earth's axis of rotation; that is, a star whose apparent...

     is indeed the chief star of the Ursa Minor.
  • Aquilo (NNE) – Isidore relates it to water (acqua), because but probably from "aquilus", because it soaks up water from the ground. Pliny says the surface of the earth "announces the approach" of Aquilo by drying, and the approach of Auster, by becoming moist "without any apparent cause". Alternative etymologies is that it derives from aquilus ("dark"), meaning either dark rainclouds (although it is not usually characterized as wet) or simply because it blows from the "land of darkness" (the far north)
  • Vulturnus (NE) – (normally SE, but placed mistakenly by Isidore in the NE, as in the Vatican table). Isidore derives its etymology from alte tornat ("thundering high"). Earlier, Seneca said it was named after a battle (reported by Livy) in which the funneling wind threw dirt into the eyes of Roman soldiers and delivered their defeat. Both are almost certainly incorrect. It is probably an old local wind, named after the hills of Volturno
    Volturno
    The Volturno is a river in south-central Italy.-Geography:It rises in the Abruzzese central Apennines of Samnium near Rocchetta a Volturno and flows southeast as far as its junction with the Calore River near Caiazzo and runs south as far as Venafro, and then turns southwest, past Capua, to...

    , southeast of Rome. Others believe it related to vulsi ("demolisher", from vellere), because of its storminess.
  • Subsolanus (E) – Isidore says it is from sub ortu solis ("from under the rising sun"). Concordant with Aulus Gellius, who further notes it is a name coined by Roman sailors.
  • Eurus (SE) – from the Greek Eus
    Eus
    Eus is a commune in the Pyrénées-Orientales department in southern France.-References:*...

     (dawn)
  • Euroauster (SSE) – compound of Eurus and Auster

     as the "black Auster", which "saddens all the sky" with rain. Possibly related to "austerus" (harsh, hot) or to shine (from a light quarter).
  • Austroafricus (SSW) – compound of Auster and Africus.
  • Africus (SW) – Isidore deduces it correctly "from Africa", a direct translation of the Greek Lips ("from Libya").
  • Favonius (W) – Isidore is probably correct in relating it to "favere", a favorable wind. He speaks of it as coming in the Spring, melting the winter frost and reviving vegetation and crops. It has also been related as a mild wind that cleared clouds and relieved the summer heat.
  • Corus (NW) – Isidore spells it Corus and says it is the same as the Caurus (the "frigid Caurus" mentioneed earlier by Virgil, but treated as distinct in Vitruvius). Isidore relates it to a 'chorus
    Greek chorus
    A Greek chorus is a homogenous, non-individualised group of performers in the plays of classical Greece, who comment with a collective voice on the dramatic action....

    ' of dancers,who "surround" heavy clouds and keep them in place. Aulus Gellius had already said something similar, but in reference to Caecias (a NE wind), not Corus. Others have related Corus to cover, conceal, because it relates to clouds, or perhaps the shower?
  • Circius (NNW) – Isidore sees its circular or "bending" etymology and (perhaps a little confusingly) suggests its name is because it "bends into" Corus. Pliny and Aulus Gellius had already identified the Circius as the Mistral
    Mistral (wind)
    The mistral is a strong, cold and usually dry regional wind in France, coming from the north or northwest, which accelerates when it passes through the valleys of the Rhone and the Durance Rivers to the coast of the Mediterranean around the Camargue region.

Vitruvius's 24-wind rose

Chronologically, Vitruvius
Vitruvius
Marcus Vitruvius Pollio was a Roman writer, architect and engineer, active in the 1st century BC. He is best known as the author of the multi-volume work De Architectura ....

, who flourished in the late 1st Century BCE, precedes all the Latin writers mentioned above: Seneca, Pliny, Aulus Gellius, etc. As such, his system of winds perhaps ought to be considered before the others. But Seneca quotes Varro
Varro

 as the source of his 12-wind system, and Varro wrote before Vitruvius. Moreover, Vitruvius's system is sufficiently distinct and peculiar to defy comparison with the others, and merits treatment in a special category all its own.

's reduction of the winds from twelve to eight principal winds. But Vitrivius then goes on to note there are many other winds, only slightly different from the core eight, which have been given a name of their own in the past. In a rather hurried fashion, Vitruvius relates an ample list of two variations on either side of the eight principal winds, which yield up a wind rose of 24 winds. Although the 24 winds might be easier to draw equally spaced at 15° from each other, they are easier to list using modern half- and quarter-wind notation. No insinuation about degrees should be read into either case (principal winds are in bold):

N Septentrio
N by E Gallicus
NNE Supernas
NE Aquilo
ENE Boreas
E by N Carbas
East Solanus
E by S Ornithiae (periodic)
ESE Eurocircias
SE Eurus
SSE Vulturnus
S by E Leuconotos
S Auster
S by W Altanus
SSW Libonotus
SW Africus
WSW Subvesperus
W by S Argestes
W Favonius
W by N Etesiae (periodic)
WNW Circius
NW Caurus
NNW Corus
N by W Thrascias


Many of the names in Vitruvius's list have appeared before elsewhere. Among the changes worth noting is the insertion of Gallicus (probably the Mistral

 lake breeze) in the very NE, nudging Aquilo (old NNE) to the NE (almost as in Pliny – perhaps the source of his confusion?). Old Boreas (now separate from Aquilo) is shunted further east – it has never been so far displaced from its ancient perch in the North. Caecias disappears from the NE altogether (although it appears on some enumerations of Vitruvius's list and will make a comeback with Seneca). Carbas, already noted as a Cyrene variant for the SE, is placed in the northeast quadrant. Latin Vulturnus is rightfully in the southeast, adjoining its Greek alternate Eurus. Greek Argestes is given here separately, adjoining Favonius in the west, albeit below its usual northwesterly quadrant. Leuconotos, previously a variant for Libonotus, is separated off and sent to the southeast quadrant (where Euronotos/Euroauster used to be, which seem to have disappeared altogether). There is nonetheless a similar-sounding Eurocircias nearby in the southeast, which might be the Biblical euroaquilo
Euroclydon
Euroclydon is a cyclonic tempestuous northeast wind which blows in the Mediterranean. It is the modern Gregalia or Levanter.-Notable references:...

.
Among other things worth noting, Solanus does not have its sub prefix and the wind Caurus (mentioned later by Aulus Gellius) is inserted between Corus and Circius (with old Thrascias given a separate position above that). Notice that Caurus and Corus are treated differently here, rather than one as just a misspelling of the other. Altanus is probably is a local reference to a seaborne breeze.

Vitruvius's 24-wind list does not seem to have impressed later Roman writers (Seneca, Pliny, etc.), who all went back to 12 or 8-wind systems. Vitruvius's treatment has a touch of carelessness. He does not bother assigning Latin-to-Greek equivalents, give variants or provide any descriptions of the winds. It seems as if he is merely making a long list of all the wind names he has heard, giving each their own separate position in a single system, regardless of duplication. The shifts of some old Greek winds (Boreas, Eurus, Argestes, Leuconotos) into non-traditional positions (sometimes even in the wrong quadrant), could reflect the relative positions of Greece and Italy – or could simply indicate that Vitruvius did not much care for this exercise, and assigned their names roughly just to get a nice symmetric system of two off-winds for every principal wind. One can almost detect a touch of mockery in his construction, almost as if to ridicule elaborate wind systems that try to push beyond the basic eight winds.

Although usually ignored, Vitruvius's list of 24 winds re-emerged occasionally. Vitruvius's list of winds was articulated again in Georgius Agricola's De Re Metallica (1556). (Per happenstance, 24-point compasses were used in celestial astronomy/astrology and in Chinese geography, but these are unrelated to Vitruvius.)

Medieval Transition

The Classical age ended with the struggle between the 12-wind rose and the 8-wind rose unresolved. Loosely speaking, it seemed as if classically-minded geographers favored the 12-wind system, but those of more practical bent preferred the 8-wind system. As the Dark Ages advanced, it could be expected for the 8-wind rose to prevail, but the guardians of classical knowledge, such as St. Isidore of Seville

 himself adopted the classical 12-wind system, replacing the Greek-Latin names with an entirely new set of Germanic names of his own invention. Einhard's lists Charlemagne's nomenclature as follows (giving their equivalence to the Latin names in St. Isidore's list):
  • (N) Nordroni
  • (NNE)Nordostroni
  • (NE) Ostnordroni
  • (E) Ostroni
  • (SE) Ostsundroni
  • (SSE) Sundostroni

  • (SSW) Sundvuestroni
  • (SW) Vuestsundroni
  • (W) Vuestroni
  • (NW) Vuestnordroni
  • (NNW) Nordvuestroni


It is interesting to note that Charlemagne's nomenclature resolves the half-wind dilemma (e.g. NNE vs. NE) by word order – Northeast and Eastnorth – giving neither a priority over the other (thus closer to NNE and ENE, with NE itself absent).

The Frankish suffix -roni means "running from" (similar to the modern English "-ern" in "Northern"). The etymology of Nord is uncertain (the suggestion from Sanskrit

  • (S) Ostro
  • (SW) Libeccio or Garbino
  • (W) Ponente

From these eight principal winds, 16-wind roses could be constructed with half-winds (NNE, ENE, etc.) which merely combined the names of the principal winds (e.g. NNE would be Greco-Tramontana, ENE Greco-Levante, and so on). 32-wind roses, which were already present in the early 1300s charts, relied on placing quarter-winds in between (the names of the quarter-winds were also just combinations of names of the principal winds (see Boxing the compass

 (Byzantine-held Calabria and Apulia was to the northeast of Arab Sicily). A substantial part of sailing knowledge acquired by the Medieval Italian seafarers came not from their Roman ancestors, but rather from Arab seafarers via Arab-Norman Sicily.

While sailors probably could not care less about the source, scholars trained in the classics of Isidore and Aristotle, were not so easily won over. The classical 12-wind rose was still being taught in the academies well into the 15th C., e.g. in Pierre d'Ailly

It is also the term for the graduated markings found on the traditional...

, in his Liber Accidentalist, attempted to reconcile the classical 12 winds he was taught with the "new" Mediterranean wind rose. In one effort, Matthew Paris assigned the 12 classical names to N, E, S, W and the half-winds (NNE, ENE, ESE, etc.), leaving the principal diagonals NE, SE, SW and NW vacant. Thus Septentrio to N, Aquilo to NNE, Vulturnus to ENE, Subsolanus to E, Eurus to ESE, Euroauster to SSE, Auster to S, and so on. (Indeed, this assignment is frequently used by many authors (but not this article) to explain the classical 12-wind system in modern terms). In a second effort, he decided to conjure up 16 classical-sounding names for all 16 winds of the mariner's rose. In his construction (noted on a scribbled corner), he seemed to contemplate the following:
  • (N) – Aquilo g.e. septentrio
  • (NNE) – Boreas aquilonaris
  • (NE) – Vulturnus borealis
  • (ENE) – Boreas orientalis
  • (E) – Subsolanus, calidus et siccus
  • (ESE) – Eurus orientalis
  • (SE) – Euro-nothus
  • (SSE) – Euro-auster, Egipcius?
  • (S) – Auster meridionalis
  • (SSW) – Euroauster affricanus
  • (SW) – Eurus procellosus
  • (WSW) – Africus occidentalis
  • (W) – Zephyrus blandus g.e. favonius
  • (WNW) – Chorus occidentalis
  • (NW) – Circius choralis
  • (NNW) – Circius aquilonaris


But Paris did not go beyond jotting these names down on a corner of the manuscript.

 made one final attempt to reconcile the classical twelve with the mariner's eight by assigning 8 of the 12 to the principal winds of the compass, and the remaining four to the half-winds NNW, NNE, SSE and SSW. In Homem's assignment:
  • Septentrio = Tramontana (N)
  • Aquilo or Boreas = Greco-Tramontana (NNE)
  • Caecias or Hellespontus = Greco (NE)
  • Subsolanus or Eurus = Levante (E)
  • Vulturnus = Scirocco (SE)
  • Euronotus = Ostro-Scirocco (SSE)
  • Auster or Notus = Ostro (S)
  • Libonotus = Ostro-Libeccio (SSW)
  • Africus or Lips = Libeccio (SW)
  • Favonius or Zephyrus = Ponente (W)
  • Corus or Caurus = Maestro (NW)
  • Circius = Maestro-Tramontana (NNW)


Homem's assignment of the 12 classical names to the modern compass happens correspond exactly to the assignment we have been using throughout this article.
