The Hermes Ludovisi, also formerly known as Mercurio Oratore ("Mercury the Orator"),[2] is a Hellenistic sculpture of the god Hermes in his form of Hermes Psychopompus. It is made of Italic marble and is a somewhat slick[3] 1st-century AD Roman copy after an inferred bronze original of the 5th century BC which is traditionally attributed to the young Phidias, ca 440 BC,[4] or alternatively called "Myronic".[5] Its model is among the earliest sculptural representations of Hermes as beardless and youthful.[6] It was acquired by Cardinal Ludovico Ludovisi for the Ludovisi collection and is now on show at the Palazzo Altemps.
