Platorius Nepos was governor of Germania Inferior. He was a close friend and possible kinsman of the Emperor Hadrian and may have accompanied Hadrian on his visit to Britain in 122. In this year he was made governor of Roman Britain and oversaw the construction of Hadrian's Wall. He probably brought VI Victrix with him from the continent to assist in the construction and perhaps to replace IX Hispana which had left around 108.
Nepos' huge expenditure on the frontier work however caused him to fall from Hadrian's favour. He was replaced around 125.
