這是羅馬奧古斯都皇帝的大理石雕像（高2.04米），約作於公元1世紀。1863年發現於羅馬城北「第一門」的莉薇亞別墅遺址，現藏梵蒂岡博物館。 雕像塑造了正在演說（adlocutio）的統帥形象。奧古斯都身穿精雕胸甲，右臂前指，姿態典雅。腳旁騎海豚的邱比特，象徵其家族奉維納斯為始祖。 胸甲浮雕是核心：中央描繪帕提亞人交還羅馬軍旗，紀念公元前20年的外交勝利；周圍諸神環繞，將皇權與宇宙秩序相聯，頌揚其帶來的和平時代。此作常被視為青銅原作的複製品。 English Introduction​ This is a marble portrait statue of Emperor Augustus (2.04 m high), created around the 1st century AD. Discovered in 1863 at the Villa of Livia in Prima Porta, Rome, it is now housed in the Vatican Museums. The statue presents Augustus in the adlocutiopose, addressing troops. He wears a finely carved cuirass, with his right arm extended. A Cupid riding a dolphin at his foot alludes to the Julian family’s divine descent from Venus. The cuirass relief is central: it shows a Parthian returning Roman military standards, commemorating the diplomatic achievement of 20 BC; surrounding gods frame his rule within a cosmic order, celebrating the ensuing peace. It is considered a copy of a lost bronze original.
