Gaius Calpetanus Rantius Sedatus

Gaius Calpetanus Rantius Sedatus was a Roman senator, who held a number of offices in the imperial service. He was suffect consul in the nundinium of March to April 47 with Hordeonius Flaccus as his colleague.^[1] He is known primarily from inscriptions.

His cursus honorum is known only piecemeal. The first known office Sedatus held was curator tabullarium publicorum in 45, a post reserved for senators of praetorian status.^[2] After he was suffect consul, the emperor Claudius appointed him governor of the province of Dalmatia.

His father was probably Gaius Calpetanus C.f. Statius Rufus.^[3] Gaius Calpetanus Rantius Quirinalis Valerius Festus, suffect consul in 71, has been identified as his adopted son.^[4]
