Pierre Julien (20 June 1731 – 17 December 1804) was a French sculptor who worked in a full range of rococo and neoclassical styles.
He served an early apprenticeship at Le Puy-en-Velay, near his natal village of Saint-Paulien, then at the École de dessin of Lyon, then entered the Parisian atelier of Guillaume Coustou the Younger.
He was a pensionnaire at the French Academy in Rome, 1768 to 1773, where he was influenced by the tide of neoclassicism that affected his fellow students.
As pensionnaires were expected to do, he sent back to France a marble copy from the Antique, slightly reduced in scale, of the so-called Cleopatra, the Vatican's Sleeping Ariadne, which remains at Versailles.
On his return to France and his former master, he worked on the sculpture for the mausoleum of Louis, le Grand Dauphin in the cathedral of Sens.
Bas-reliefs from the Laiterie, reckoned among his masterpieces, were sold at auction in 1819, but were retrieved by the State in 2005, thanks to a gift from the son of the great dealer-collector Daniel Wildenstein.
