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
) 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.
