Here'nnius
6. M.
Herennius, was consul in B. C. 93. (Fast.; Obseq. 112.) Although a plebeian and an indifferent orator, he carried his election against the high-born and eloquent L. Marcius Philippus. (
Cic. Brut. 45,
pro Muren. 17.) Pliny (
Plin. Nat. 19,
3) mentions the consulate of Herennius as remarkable for the quantity of Cyrenaic silphium--
ferula Tingitana (Sprengel,
Rei Herbar. p. 84.), then brought to Rome.
This costly drug was worth a silver denarius the pound; and the mercantile connections of the Herennii in Africa may have caused this unusual supply.
