1. a Roman senator. During the praetorship of C. Sacerdos he had become possessed of an estate in Sicily by the will of one C. Sulpicius Olympus. When Verres became praetor, in accordance with one of his edicts the daughter of the patronus of Sulpicius sued Ligur for a sixth part of the estate. Ligur found himself compelled to come to Rome to assert and defend his rights. Verres afterwards demanded money from Ligur for trying the cause. M. Ligur and his brother are set down as tribunes of the plebs in the same year (B. C. 82) by Pighius (vol. iii. p. 266). (Cic. in Verr. 1.48, 2.7, 48.)
