Ancient Greek
p. 6982 ⟨Ἀρείου Διδύμου⟩ · 1
Ἀριστοτέλους. Ἅλω δὲ καὶ ἴριδας καὶ παρήλιον καὶ ῥάβδους καὶ τἆλλα τὰ κατὰ τὰς ἐμφάσεις ὑπὸ μὲν τῆς αὐτῆς αἰτίας γίνεσθαι· πάντα γὰρ εἶναι ταῦτα τῆς ὄψεως ἀνάκλασιν, διαφέρειν δὲ τοῖς τρόποις καὶ ἀφ᾽ ὧν καὶ ὡς ἔχειν συμβαίνει τὴν ἀνάκλασιν.
2 ⟨Ἀρείου Διδύμου⟩ · 2
Ἅλω μὲν οὖν καὶ περὶ ἥλιον φαίνεσθαι καὶ περὶ σελήνην καὶ καθόλου περὶ τὰ λαμπρὰ τῶν ἄστρων καὶ οὐθὲν ἧττον ἡμέρας ἢ νυκτὸς καὶ περὶ μεσημβρίαν ἢ δείλην· ἕωθεν δ᾽ ἐλαττονάκις καὶ περὶ δύσιν. Συμβαίνειν δ᾽, ὅταν διὰ τοῦ πέριξ ἀέρος ἀχλυώδους ὄντος ἐπιλάμπηται τὸ φῶς αὐτῶν, ὥσθ᾽ ὅλον ὁρᾶσθαι τὸν κύκλον· περιφανῆ γὰρ εἶναι καὶ σφαιρικὴν κατὰ τὴν ἔμφασιν τὴν ἅλω.

Ταύτης δὲ τὴν μὲν ἐπιμένουσαν ὑετὸν σημαίνειν, τὴν δὲ διασπασθεῖσαν πνεῦμα, τὴν δὲ μαραινομένην εὐδίαν.
Stobaeus, Volume I: Book I Chapter 30
p. 6992 ⟨Arius Didymus⟩: Aristotle on reflection
Aristotle’s view. Halos, rainbows, mock suns, rods, and the other phenomena that are appearances arise from the same cause. All are reflections of sight, differing in their modes, in the surfaces from which the reflection occurs, and in the conditions under which it takes place.896
2 Aristotle: Where halos appear
A halo appears around the sun and the moon, and generally around bright stars, no less by day than by night, at midday or in the afternoon; less often in the morning and around sunset. It occurs when their light shines through the surrounding air while it is hazy, so that the whole circle is seen: the halo is visible all around and round in appearance.897
2 Aristotle: Halos as weather signs
A halo that persists signifies rain; one that breaks apart, wind; and one that fades, fair weather.898
