(Τισίφονος), the eldest brother of Thebe, the wife of Alexander of Pherae, in whose murder he took part with his sister and his two brothers, Lycophron and Peitholaus. After Alexander's death, according to Conon the grammarian, Thebe virtually governed, while Tisiphonus held the nominal authority. Xenophon simply mentions him as Alexander's successor, and Diodorus tells us that he and Lycophron held the tyranny together, maintaining themselves by cruelty and violence with the aid of a mercenary force. We do not know how long the reign of Tisiphonus lasted; but he appears to have been dead by B. C. 352, when Philip of Macedon marched into Thessaly to support the Aleuadae against Lycophron. (Xen. Hell. 6.4.37; Diod. 16.14; Con. Narr. 50 ; Plut. Pel. 35 ; Clint. F. H. vol. ii. App. ch. 15.)
