Laert. 10,26). Cicero praises T.'s 'wisdom' (sapientia) and names her as the author of numerous writings (tanta volumina, Cic. Pis. 63). Epicurus addressed a number of letters (Excerpt: Diog. Laert. 10,5 = fr. 125 Usener) and a work Neocles to T. (Νεοκλῆς πρὸς Θεμίστα; Diog. Laert. 10,28) to her. Nothing of her work survives.
