Caesar decided to construct a forum bearing his name in the northeast section of the Forum Romanum, and purchased some very expensive parcels of land in that area. Forum construction began probably in 51 BC, although Cicero and Gaius Oppius were entrusted with purchasing the parcels of land on Caesar's behalf as early as 54 BC. On the eve of the Battle of Pharsalus in 48, Caesar vowed a temple to Venus Victrix, the legendary progenitor of his own clan, the gens Iulia. This original dedication was done because she was Pompey's favourite goddess, and Caesar hoped to gain the goddess's favour before the battle against Pompey.
