Himilco , the name of several distinguished Carthaginians, the most eminent of whom were the following: I. A navigator, who lived in the 6th or 5th century B. C., and who was sent on a voyage of discovery northward from Gades at the same time that Hanno was commissioned to explore and colonize the W. coast of Africa. On his return he is said to have reported that the stagnant nature of the sea, the vast mass of seaweed that floated on its surface, and the absence of wind, had prevented his progress toward the north. II. A general who commanded, in conjunction with Hannibal the son of Gisco, the third expedition sent by the Carthaginians to Sicily (40G B. C). The latter having been carried off by sickness soon after their arrival, Himilco succeeded to the command. Having reduced Agrigentum and destroyed several of the Greek cities, he concluded an advantageous peace with Dionysius the Elder, tyrant of Syracuse, and returned to Africa, When Dionysius declared war against Carthage, and attacked her dominions in Sicily, Himilco was appointed to defend them.

Being worsted, he retired from Sicily, but in the following spring returned with a powerful force, and after recovering the greater part of the lost territory advanced against Syracuse. This enterprise failed, and Himilco concluded an ignominious peace, returned to Carthage, and committed suicide by starvation.
