Androtion, FGrH 324 F 6, and Aristotle, Ath. Pol. 22, seem to differ about the date when ostracism was introduced in Athens. But the words τότє πρῶτον in the text of Androtion have been attacked as unsatisfactory Greek. I hold that, on the contrary, they are perfectly acceptable and idiomatic.
For reference, I cite the text of Androtion, which is quoted in the lexicon of Harpocration, and of Aristotle.
Harpocration, s.v. Ἵππαρχος … ἄλλος δέ ἐστιν Ἵππαρχος ὁ Χάρμου … περὶ δὲ τούτου Ἀνδροτίων ἐν τῇ β̄ φησὶν ὅτι συγγενὴς ἦν Πεισιστράτου τοῦ τυράννου καὶ πρῶτος ἐξωστρακίσθη, τοῦ περὶ τὸν ὀστρακισμὸν νόμου τότε πρῶτον τεθέντος διὰ τὴν ὑποψίαν τῶν περὶ Πεισίστρατον, ὅτι δημαγωγὸς ὢν καὶ στρατηγὸς ἐτυράννησεν.
