The recent revival of scholarly interest in Suetonius provides a good occasion to emend a long-standing crux in Joannes Lydus' description (De Mag. 2.6) of Suetonius' dedication of his Vitae Caesarum to his friend the praetorian prefect Septicius Clarus. The codex unicus Caseolinus (Parisinus suppl. gr. 257, s. X/XI) has Τράγκυλλος τοίνυν τοὺς τ⋯ν Καισάων βίους ⋯ν γράμμασιν † ⋯ποτίνων † Σεπτικίῳ, ὃς ἦν ὓπαρχος τ⋯ν πραιτωριαν⋯ν σπειρ⋯ν ⋯πì αὐτο⋯. The conjectures ⋯ποτείνων by J. D. Fuss and ὑποτείνων by I. Bekker do little to improve the sense, and although W. Kroll's προτείνων gives the meaning required by the context (cf. Aristophanes, Plut. 1019), προ- would not easily have been misread as ⋯πο-.
For ⋯ποτίνων read ⋯νατείνων. For parallels compare BGU ii (1898), 613.3–4 'Ανέτινα ( = 'Ανέτεινα) βιβλ[ίδι]α τῷ λαμπροτάτῳ [⋯γεμόνι] in a papyrus from the reign of Antoninus Pius cited by LSJ, and several other passages, most of which I owe to the supplement to Preisigke and Kiessling's Wörterbuch der griechischen Papyrusurkunden and to Dr Francisco R.
