In addition to the sources listed below, Stevens points to a reference to Σωδίνων from a list of canonographers from a Vatican Aratea manuscript (Vat gr. 381). Vettius Valens Ἔδοξεν οῦν μοι χρῆσθαι Ἱππάρχῳ μέν πρός τόν Ἥλιον, Σουδίνῃ δέ καὶ Ἀπολλωνίῳ πρός τήν Σελήνην, ἔτι δέ καὶ Ἀπολλιναρίῳ πρός ἀμφότερα τά ἔιδη (Vettius Valens Anthologies 9.12) "I thought it best to use Hipparchus for the sun, Sudines, Kidenas, and Apollonius for the moon, in addition to Apollinarius for both bodies." Strabo ἔστι δὲ καὶ τῶν Χαλδαίων τῶν ἀστρονομικῶν γένη πλείω: καὶ γὰρ Ὀρχηνοί τινες προσαγορεύονται καὶ Βορσιππηνοὶ καὶ ἄλλοι πλείους ὡς ἂν κατὰ αἱρέσεις ἄλλα καὶ ἄλλα νέμοντες περὶ τῶν αὐτῶν δόγματα. μέμνηνται δὲ καὶ τῶν ἀνδρῶν ἐνίων οἱ μαθηματικοί, καθάπερ Κιδήνα τε καὶ Ναβουριανοῦ καὶ Σουδίνου: καὶ Σέλευκος δ᾽ ὁ ἀπὸ τῆς Σελευκείας Χαλδαῖός ἐστι καὶ ἄλλοι πλείους ἀξιόλογοι ἄνδρες.(Strabo Geographia 16.1.6) "There are many kinds of Chaldaean astronomers: Some are called Orcheni and Borsippeni and many others, as if divided into sects, who dispense different opinions on the same subjects. The mathematicians make mention of some of these men, such as Kidenas and Nabourianos and Sudines. And Seleucus from Seleuceia is a Chaldaean, and more remarkable men.” Pliny the Elder Nec in Acarnania ante laudati reperiuntur, enormes et fere coloris marmorei. meliores circa Actium, sed et hi parvi, et in Mauretaniae maritimis. Alexander polyhistor et Sudines senescere eos putant coloremque expirare. (Historia Naturalis IX.56) "And there are not found in Acarnania the formerly celebrated pearls of an exceptional size and almost a marble colour. Better ones are found round Actium, but these too are small, and in sea-board Mauretania. Alexander the Encyclopaedist and Sudines think that they grow old and let their colour evaporate." Onychem in Arabiae tantum montibus nec usquam aliubi nasci putavere nostri veteres, Sudines in Carmania. (Historia Naturalis XXXVI.12) "Onyx marble was supposed by our old authorities to occur in the mountains of Arabia and nowhere else. Sudines, however, thought that it occurred in Carmania." hoc mirum quod Xenocrates Ephesius tradit, aratro in Asia et Cypro excitari; non enim reperiri in terreno nec nisi inter cautes creditum fuerat. similius veri est, quod idem Xenocrates tradit, et torrentibus saepe deportari. Sudines negat nisi ad meridiem spectantibus locis nasci. (Historia Naturalis XXXVII.9) "The surprising remark is made by Xenocrates of Ephesus that in Asia Minor and Cyprus rock-crystal is turned up by the plough, for previously
