HIEMPSAL, the name of the two kings of Numidia. For Hiempsal I. see under Jugurtha. Hiempsal II. was the son of Gauda, the half-brother of Jugurtha. In 88 B.C., after the triumph of Sulla, when the younger Marius fled from Rome to Africa, Hiempsal received him with apparent friendliness, his real intention being to detain him as a prisoner. Marius discovered this intention in time and made good his escape with the assistance of the king’s daughter. In 81 Hiempsal was driven from his throne by the Numidians themselves, or by Hiarbas, ruler of part of the kingdom, supported by Cn. Domitius Ahenobarbus, the leader of the Marian party in Africa. Soon afterwards Pompey was sent to Africa by Sulla to reinstate Hiempsal, whose territory was subsequently increased by the addition of some land on the coast in accordance with a treaty concluded with L. Aurelius Cotta. When the tribune P. Servilius Rullus introduced his agrarian law (63), these lands, which had been originally assigned to the Roman people by Scipio Africanus, were expressly exempted from sale, which roused the indignation of Cicero (De lege agraria, i. 4, ii. 22). From Suetonius (Caesar, 71) it is evident that Hiempsal was alive in 62. According to Sallust (Jugurtha, 17), he was the author of an historical work in the Punic language.
