Marcus Herennius was consul of the Roman Republic in 93 BC. Although a plebeian and an indifferent orator, he defeated Lucius Marcius Philippus in the consular election for 93 BC.Defence speeches, by Marcus Tullius Cicero, translated by D. H. Berry, Oxford University Press 2000. p. 237. PlinyH.N. 19.3 mentions the consulate of Herennius as remarkable for the quantity of Cyrenaic silphium -- Ferula tingitanaSprengel, Rei Herbar., p. 84 -- then brought to Rome. This costly drug was worth a silver denarius per pound; and the mercantile connections of the Herennii in Africa may have caused this unusual supply.
