(Ἠγήσιππος), 1. An Athenian of the time of Demosthenes, and the brother of Hegesander, was nicknamed Κρωβύλος by Aeschines, but for what reason is quite uncertain. He was of the same political party as Demosthenes. He advocated the Phocian alliance, and the declaration of war against Philip, who showed his resentment by his conduct towards Hegesippus in the celebrated Macedo ian embassy. He was also united with Demosthenes in his mission to excite the Peloponnesians to make war with Philip. He defended Timarchus, when accused by Aeschines, and accused Callippus. The ancient grammarians ascribe to him two of the orations which have come down to us as those of Demosthenes, namely, that on Halonesus, and that on the treaty with Alexander. (Dem. de Fals.
