Hippolyte Alexandre Julien Moulin, sometimes given as Julien-Hippolyte Moulin or Hypolite Moulin, (1832–1884) was a 19th-century French sculptor.
Moulin, a shopkeeper's son, entered the École des Beaux-Arts in 1855 but was unable to afford to continue the lessons and had to become a language teacher in Paris to support himself.
He subsequently studied with Auguste-Louis-Marie Ottin and with Antoine-Louis Barye.
His bronze statue A Lucky Find at Pompeii (Une Trouvaille à Pompei) (1863) depicts a nude boy with a spade dancing for joy with one leg raised, because he has unearthed a Roman statuette.
His nude pose reflects that of the statuette itself, possibly indicating that the statue depicts the excavator imagining himself in the original statuette's pose.
The statue won a medal at the Paris Salon of 1864 and became his most famous work.
The life-size original was bought by the French Government for 7,000 francs and exhibited at the Exposition Universelle in 1867.
