The project, which brought a first virtual confrontation with Roman sculpture to French patrons and artists, is surveyed in detail by S. Pressouyre, "Les fontes de Primatice à Fontainebleau", Bulletin monumental127 (1969), pp. 223-38. See also Thomas Clouet, "Fontainebleau de 1541 à 1547. Pour une relecture des Comptes des Bâtiments du roi", Bulletin monumental170 (2012), pp. 195-234, in which article a precise chronology of the casting of these famous bronzes is established (english summary). The precious moulds, at the instigation of Leone Leoni were sent to the Habsburg court in the Spanish Netherland in 1550 and, after serving to make a set of stucco casts for Charles V's daughter Mary of Hungary, Queen-governess of the Netherlands at Binche (where they were destroyed by Henry II's troops in 1554) they were probably forwarded to Leoni in Milan (Bruce Boucher, "Leone Leoni and Primaticcio's Moulds of Antique Sculpture", The Burlington Magazine123 No. 934 (January 1981), pp. 23-26).
