Τούτου δὲ πάλιν τὸ μὲν τι καλεῖται ἑσπερία ἐπικατάδυσις φαινομένη, ὅταν ὁ ἀστὴρ ἀρχόμενος κρύψιν ποιεῖσθαι μετὰ τὸν ἥλιον εὐθὺς αὐτὸς καταδύνῃ, τὸ δέ τι καλεῖται ἑσπερία συγκατάδυσις ἀληθινή, ὅταν ὁ ἀστὴρ ἅμα καὶ κατὰ τὸ αὐτὸ τῷ ἡλίῳ καταδύνῃ, τὸ δέ τι καλεῖται ἑσπερία πρόδυσις μὴ φαινομένη, ὅταν ὁ ἀστὴρ ἀρχόμενος ἐπιτολὴν ποιεῖσθαι προκαταδύνῃ τοῦ ἡλίου.
‘And from this again, one is called evening appearing following setting, when the star beginning to make its disappearance sets itself immediately after the sun, and another one is called evening apparent simultaneous setting, when the star sets together with and at the same time as the sun, and yet another one is called evening non-appearing leading setting, when the star beginning to make its heliacal rising sets earlier than the sun.’
