Lucius Pullaienus Gargilius Antiquus was a Roman senator, who held a number of offices in the imperial service during the reign of Antoninus Pius.
His cursus honorum is partially known from an inscription set up at Marmaraereglisi / Perinthus in Thracia.
He was appointed quaestor as a candidate of the emperor, and upon completion of this traditional Republican magistracy Antiquus would be enrolled in the Senate.
After stepping down as praetor, Antiquus was appointed curator of the viae tres Trajana: the Via Clodia, Via Cassia, and Via Ciminia; Alföldy dates this office from around the year 152 to around 155.
[4] The third office he held before acceding to the consulate was as governor of the imperial province of Thracia, which Alföldy dates from around the year 158 to around 161.
