Since writing my paper on Cleostratus, I have received from Professor Boll a copy of his masterly treatise, Antike Beobachtungen farbiger Sterne, in which he incidentally deals with the πρῶτα σημεῖα of Cleostratus, which he identifies with the sign Libra. This interpretation is based on an excerpt from Antiochus, dealing with the pernicious degrees of the zodiac. The passage runs as follows:—

Κέντρον Σκορπίου ἀπὸ ἔως ί κράσεως ᾿ Αρεως καὶ Κρόνου καὶ <ἡ>πρώτη μοῖρα κράσεως ῾ Ερμοῦ κτλ

Professor Boll recognises that the words ἀπὸ . . . Κρόνου cannot refer to the Scorpion's sting, and supposes that after Σκορπίου the words τὸμέτωπον τοῦ Σκορπίου have fallen out. He then takes ἡ πρώτη μοῖρα as equivalent to the πρῶτα σημεῖα of Cleostratus, a traditional phrase unlike the terminology of the rest of the passage.
