Maturus, Marius
was procurator of the maritime Alps in the war between Otho and Vitellius, A. D. 69, and enlisted on the side of the latter the mountaineers of his district. After Otho's death Maturus retained his post and was for some time faithful to Vitellius. But as he was nearly surrounded by the enemy in Narbonne and Cisalpine Gaul, and could not rely on the valour or fidelity of his Alpine levies, he reluctantly transferred his allegiance to Vespasian. (Tac. Hist. 2.12, 13, 3.42, 43.)
