Signs of Winds from Lightning, Clouds, and Wind Shift Rules

Passage 5 of 8 · Greek

Summary

This section explains signs for predicting the generation and cessation of winds through lightning, thunder, celestial movements, and mountain clouds, while detailing the characteristics and shifts of specific winds based on the ancient wind rose.

§2.32Ἐὰν ἀστραπὴ πανταχόθεν γίνηται, ὕδωρ σημαίνει, καὶ ὅθεν ἂν αἱ ἀστραπαὶ πυκναὶ γίνωνται, ἐντεῦθεν πνεύματα γίνεται.
If lightning occurs from all sides, it indicates rain; and from whichever quarter the lightning is frequent, from there winds will arise.
θέρους ὅθεν ἂν ἀστραπαὶ καὶ βρονταὶ γίνωνται, ἐντεῦθεν πνεύματα γίνεται ἰσχυρά· ἐὰν μὲν σφόδρα καὶ ἰσχυρὸν ἀστράπτῃ, θᾶττον καὶ σφοδρότερον πνεύσουσιν, ἐὰν δ᾿ ἠρέμα καὶ μανῶς, κατ᾿ ὀλίγον.
In summer, from whichever quarter lightning and thunder occur, from there strong winds will arise; if the lightning is violent and intense, they will blow more quickly and violently, but if gentle and sparse, gradually.
τοῦ δὲ χειμῶνος καὶ φθινοπώρου τοὐναντίον· παύουσι γὰρ τὰ πνεύματα αἱ ἀστραπαί· καὶ ὅσῳ ἂν ἰσχυρότεραι γίνωνται ἀστραπαὶ καὶ βρονταί, τοσούτῳ μᾶλλον παύονται·
In winter and autumn, however, the opposite is true; for the lightning ceases the winds; and the more intense the lightning and thunder are, the more they cease.
τοῦ δ᾿ ἔαρος ἧττον ἂν ταὐτὰ σημεῖα λέγω, ὥσπερ καὶ χειμῶνος.
In spring, I would say the same signs apply, though to a lesser degree than in winter.
§2.33Ἐὰν νότου πνέοντος βορρᾶθεν ἀστράπτῃ, παύεται·
If lightning occurs from the north when a south wind is blowing, the wind ceases.
ἐὰν ἕωθεν ἀστράπτῃ εἴωθε παύεσθαι τριταῖος, οἱ δὲ ἄλλοι πεμπταῖοι ἑβδομαῖοι ἐναταῖοι, οἱ δὲ δειλινοὶ ταχὺ παύονται.
If it lightens at dawn, the wind is accustomed to cease on the third day; other winds cease on the fifth, seventh, or ninth days, while those from evening lightning cease quickly.
οἱ βορέαι παύονται ὡς ἐπὶ τὸ πολὺ ἐν περιτταῖς οἱ δὲ νότοι ἐν ἀρτίαις.
North winds cease for the most part on odd days, and south winds on even days.
ἄνεμοι αἴρονται ἁμ᾿ ἡλίῳ ἀνατέλλοντι καὶ σελήνῃ.
Winds rise along with the rising sun and moon.
ἐὰν ἀνατέλλων ὁ ἥλιος καὶ σελήνη παύσωσιν, ἐπιτείνει τὰ πνεύματα· χρονιώτερα δὲ καὶ ἰσχυρότερα τὰ πνεύματα γίνεται τὰ ἡμέρας ἢ νύκτωρ ἀρχόμενα.
If the winds cease when the sun and moon rise, they afterwards intensify; and those winds that begin by day are more long-lasting and stronger than those starting by night.
§2.34Ἐὰν ἐτησίαι πολὺν χρόνον πνεύσωσι καὶ μετόπωρον γένηται ἀνεμῶδες, ὁ χειμῶν νήνεμος γίνεται, ἐὰν δ᾿ ἐναντίως, καὶ ὁ χειμὼν ἐναντίος.
If the Etesian winds blow for a long time and autumn becomes windy, the winter becomes calm; but if on the contrary, the winter is also contrary.
πρὸς κορυφῆς ὄρους ὁπόθεν ἂν νεφέλη μηκύνηται, ταύτῃ ἄνεμος πνευσεῖται.
From whichever part of a mountain peak a cloud is elongated, in that direction the wind will blow.
αἱ νεφέλαι ἐκ τῶν ὄπισθεν προσίζουσαι καὶ ὄπισθεν πνευσοῦνται.
Clouds settling from behind indicate that the wind will also blow from behind.
Ἄθως μέσος διεζευγμένος νότιος, καὶ ὅλως τὰ ὄρη διεζωσμένα νότια ὡς τὰ πολλά.
Mount Athos divided in the middle is a sign of a south wind, and in general, mountains girdled with clouds are for the most part signs of a south wind.
οἱ κομῆται ἀστέρες ὡς τὰ πολλὰ πνεύματα σημαίνουσιν, ἐὰν δὲ πολλοί, καὶ αὐχμόν.
Comets for the most part indicate winds, and if many, drought as well.
μετὰ χιόνα νότος, μετὰ πάχνην βορέας εἴωθε πνεῖν.
A south wind is accustomed to blow after snow, and a north wind after hoar-frost.
μύκητες ἐπὶ λύχνου νότιον πνεῦμα ἢ ὕδωρ σημαίνουσιν.
Snuffs on a lamp-wick indicate a south wind or rain.
§2.35Αἱ δὲ στάσεις τῶν πνευμάτων οὕτως ἔχουσιν ὡς ἐν τῷ γράμματι διώρισται.
The positions of the winds are as defined in the diagram.
τῶν δ᾿ ἀνέμων ἔτι πνέουσι τοῖς ἄλλοις ἐπιπίπτουσι μάλιστα ἀπαρκτίας θρακίας ἀργέστης.
Among the winds, those that especially fall upon others while they are still blowing are Apartias, Thracias, and Argestes.
ὅταν δὲ μὴ ὑπ᾿ ἀλλήλων διαλύωνται τὰ πνεύματα, ἀλλ᾿ αὐτὰ καταμαρανθῶσι, μεταβάλλουσιν εἰς τοὺς ἔχομένους ἐπὶ δεξιά, ὥσπερ ἡ τοῦ ἡλίου ἔχει φορά.
When winds are not dissolved by one another, but decay of themselves, they change into those situated next on the right, just as the course of the sun goes.
ὁ νότος ἀρχόμενος ξηρὸς τελευτῶν δὲ ὑγρός. καὶ ὁ εὖρος.
The south wind is dry when it begins, but wet when it ends; and so is Eurus.
ὁ δ᾿ ἀπηλιώτης ἀπὸ ἀνατολῆς ἰσημερινῆς ὑδατώδης· διὰ λεπτῶν δὲ ἄγει τὰ ὕδατα.
Apeliotes, the wind from the equinoctial sunrise, is wet, bringing rain in light showers.
§2.36Ὑγροὶ δὲ μάλιστα ὅ τε καικίας καὶ λίψ· χαλαζώδης δ᾿ ἀπαρκτίας καὶ θρακίας καὶ ἀργέστης· νιφετώδης δὲ ὅ τε μέσης καὶ ἀπαρκτίας· καυματώδης δὲ νότος καὶ ζέφυρος καὶ εὖρος· οἱ μὲν οἷς ἂν ἐκ πελάγους προσπίπτωσιν, οἱ δὲ οἷς ἂν διὰ γῆς.
The wettest winds are Kaikias and Lips; while Apartias, Thracias, and Argestes bring hail; Meses and Apartias bring snow; and the south wind, Zephyros, and Eurus bring heat—the latter three to those upon whom they fall from the sea, and the former to those upon whom they fall through the land.
δασύνουσι δ᾿ οὐρανὸν νέφεσι καὶ καλύπτουσι καικίας μάλιστα εἶτα λίψ.
Kaikias especially, and then Lips, thicken the sky with clouds and cover it.
καὶ οἱ μὲν ἄλλοι ἄνεμοι ἀφ᾿ ἑαυτῶν τὰ νέφη ὠθοῦσι, καικίας δὲ μόνος πνέων εἰς ἑαυτόν.
And while the other winds push the clouds away from themselves, Kaikias alone when blowing draws them toward itself.
αἴθριοι δὲ μάλιστα θρακίας καὶ ἀργέστης καὶ τῶν λοιπῶν ἀπαρκτίας· ἐκνεφίαι δὲ μάλιστα ὅ τε ἀπαρκτίας καὶ ὁ θρακίας καὶ ὁ ἀργέστης.
Thracias, Argestes, and, among the rest, Apartias bring fair weather; while Apartias, Thracias, and Argestes especially bring squalls.
§2.37Γίνονται δὲ ἐκνεφίαι ὅταν εἰς ἀλλήλους ἐμπίπτωσι πνέοντες μάλιστα μὲν μετοπώρου τῶν δὲ λοιπῶν ἔαρος.
Squalls occur when winds blow against one another, especially in autumn, and among the other seasons, in spring.
ἀστραπαῖος δὲ θρακίας καὶ ἀργέστης καὶ ἀπαρκτίας καὶ μέσης.
Thracias, Argestes, Apartias, and Meses are accompanied by lightning.
ἐὰν ἐν τῇ θαλάττῃ πάπποι φέρωνται πολλοὶ οἱ γινόμενοι ἀπὸ τῶν ἀκανθῶν, ἄνεμον σημαίνουσιν ἔσεσθαι μέγαν.
If many thistledowns are carried over the sea, they indicate that there will be a great wind.
ὅθεν ἂν ἀστέρες διᾴττωσι πολλοί, ἄνεμον ἐντεῦθεν· ἐὰν δὲ πανταχόθεν ὁμοίως, πολλὰ πνεύματα σημαίνουσι.
From whichever direction many shooting stars run, the wind comes from there; and if they run similarly from all sides, they indicate many winds.
Πνευμάτων μὲν οὖν σημεῖα ταῦτα.
These, then, are the signs of winds.

Notes

  1. 2.32τοῦ δ᾿ ἔαρος ἧττον ἂν ταὐτὰ σημεῖα λέγω, ὥσπερ καὶ χειμῶνος — This passage has manuscript variations, read either as ἂν λέγω (a non-standard combination of the subjunctive with the particle ἂν) or ἂν λέγοιμι (potential optative). The meaning is 'in spring, I would say the same signs apply, though to a lesser degree than in winter.' The comparative ἧττον indicates that the signs are less certain than in winter but still relevant.
  2. 2.33ἐὰν ἀνατέλλων ὁ ἥλιος καὶ σελήνη παύσωσιν — The subject of the intransitively used verb παύσωσιν is the winds. Thus, it means 'if the winds cease when the sun and moon rise.' This contrasts with the preceding statement that 'winds rise with the rising sun and moon,' describing an exceptional intensification when the expected wind instead falls silent.
  3. 2.34αἱ νεφέλαι ἐκ τῶν ὄπισθεν προσίζουσαι — The participle προσίζουσαι means 'settling on' or 'clinging to.' The phrase ἐκ τῶν ὄπισθεν ('from behind') refers to the far side of the mountain peak, or the side away from the observer. It describes clouds clinging to the reverse side of the summit, portending that wind will also blow from that direction (ὄπισθεν πνευσοῦνται).
  4. 2.35μεταβάλλουσιν εἰς τοὺς ἐχομένους ἐπὶ δεξιά — This describes the clockwise transition of wind directions when winds decay naturally. The shift is toward 'the winds situated next on the right' (τοὺς ἐχομένους ἐπὶ δεξιά), which corresponds to the path of the sun (from east to south, west, and north), indicating veering (clockwise rotation).
  5. 2.36καικίας δὲ μόνος πνέων εἰς ἑαυτόν — This refers to a famous meteorological paradox in ancient Greece (also found in Aristotle's Meteorologica) that 'Kaikias (the north-east wind) alone draws [clouds] toward itself as it blows.' While other winds push clouds away, Kaikias appears to attract wet air and clouds back toward its own direction.
