Possibly named Marcus Vitruvius Mamurra (if we follow Thielscher's 1969 suggestion based on an inscription in Thibilis), he was an equestrian who originally came from the Italian city of Formiae.
Neither association, however, is borne out by De Architectura (which Vitruvius dedicated to Augustus), nor by the little that is known of Mamurra.
At the centre of the villa at the highest point of the promontory was a grandiose octagonal building also known as the Temple of Janus, which was flanked by two wings and two porticos sloping down towards the sea.
Catullus attacked Mamurra's profligacy, womanising and scandalous lifestyle, nicknaming him "mentula" (a vulgar word for the penis) and accusing him of having a homosexual relationship with Caesar.
[16] Catullus also refers in unflattering terms to Ameana, the mistress of "the bankrupt of Formiae", usually taken to mean Mamurra.
