The ribbed panel, in whose lunette is depicted the Trinity with angels in adoration, constitutes an ex voto for an escaped shipwreck. In the center is the Virgin and Child between St. John the Baptist, in the typical act of pointing to Jesus, and the apostle St. James the Greater; below, kneeling, is the commissioner and, to the left, a ship at the mercy of the waves, about to crash against the coast, where the so-called rocchetta of Piombino seems to be recognized.
The style would place it in the Palermitan pictorial milieu close to the modes of Vincenzo da Pavia.
The inscription bears the name of the commissioner, Giacomo Galluppi, and documents the itineraries of the ship depicted here:
“Io Iacobo Galuppo de Lipari, partendome da Ligurno cho la mia nave per [viarmi a?] Napuli se mosse uno temporale che stra[cciò] tutte i vele et andai ad corere ala plaga di Var- de Piumbino et me recom[a]ndai a Nostra Domina et fui liberato di tale furtun[…].”
