"Was an Italian sculptor during the Rococo period.
Sanmartino was born in Naples. His first dated (1753) work is The Veiled Christ or Christ lying under the Shroud, commissioned initially by the Venetian sculptor Antonio Corradini who did not live to complete the work. Sammartino interpreted his sketches freely to create a masterful sculpture which can be seen in Sansevero Chapel (also called Cappella Sansevero or Pietatella) in Naples. Other contributors to this chapel were Francesco Celebrano and the Genoese sculptor Francesco Queirolo.
The statue of Veiled Christ is elaborately artificial (art historian Wittkower labeled it as a hypertrophic effort) by reproducing in stone, the effect of a thin veil. In the same chapel, Corradini's antecedent statue of Chastity (also called Modesty) is present.
Successful completion of this commission earned Sammartino further commissions. These included the group of St. Augustine in the Neapolitan church of Sant'Agostino alla Zecca, the decoration of the Annunziata church, and the monument to Philip of Calabria in the Basilica of Santa Chiara. He also executed a series of nativity scenes."
