4. Father of Hasdrubal, who was general in Spain, together with Hasdrubal and Mago, the two sons of Hamilcar Barca. (Liv. 24.41; Plb. 9.11.) It is not improbable that this Gisco may be the same with the preceding one. Livy also calls the Hamilcar who was governor of Malta at the beginning of the second Punic war, son of Gisco (Liv. 21.51); but whether this refers to the same person we have no means of ascertaining.
