The Basilica del Santo Crucifix is a 1444–1447 bronze sculpture by Donatello on the high altar of the Basilica of Saint Anthony of Padua in Padua. It measures 180 by 166 cm; his only monumental bronze on that scale prior to that date had been his 1423–1425 Saint Louis of Toulouse. The work was originally nude, with a textile loincloth probably intended to be added; the current bronze one is a Baroque addition. The work also marks a development away from the exaggerated realism of his youthful Santa Croce Crucifix.
