Actually, set in terra-cotta and then stone.
Francesco Ladatte was an Italian who traveled to Paris with Prince Carignan at the age of 12. After a return trip to Rome, Ladatte created this model in terra-cotta when he was back to Paris in 1738.
Obviously not satisfied, Ladatte then exhibited a different terra-cotta model for “Judith resting on the head of Holofernes” at the Paris Salon in 1939 (now in the Musée de Chambéry).
Based on the submission of a small marble sculpture of “Judith resting on the head of Holofernes” (the statue in the Louvre), he was accepted at the Académie Royale in 1741.
Wonder what he didn’t like about the first one.
