II. J.) PATERCULUS, MARCUS 2 VELLEIUS, a Roman historian, was probably born about 19 B.C. His father, a cavalry officer, belonged to a good Capuan family, several members of which had risen to some military or magisterial distinc tion. The historian himself served as military tribune in Thrace, Macedonia, Greece, and the East, and in 2 A.D. was present at the interview on the Euphrates between C. Ctesar (grandson of Augustus) and the Parthian king. Afterwards as prsefect of cavalry and legatus he served for eight years (from 4 A.D. onward) in Germany and Pannonia under Tiberius, in whose triumph (12 A.D.) he and his brother bore a conspicuous part. For his services 1 For further information on the subject the reader is referred to Johnson s Patentee s Manual, fifth edition, 1884. 2 Marcus is the name given by Priscian ; but Renier identifies the historian with the " C. Velleio Paterculo " of a North-African mile stone (Aco.d. des Inscr., Dec. 1875; Rev. Archeol., 1875), the date of which he places (on inconclusive grounds) iu 3ti A.D.
