How many men returned to Spain from the original crew of Ferdinand Magellan's first circumnavigation of the Earth?

When Victoria, the one surviving ship and the smallest carrack in the fleet, returned to the harbor of departure after completing the first circumnavigation of the Earth, only 18 men out of the original crew were on board.

Among the survivors were two Italians, Antonio Pigafetta and Martino de Judicibus. Martino de Judicibus (Spanish: Martín de Judicibus) was a Genoese or Savonese Chief Steward. His history is preserved in the nominative registers at the Archivo General de Indias in Seville, Spain. The family name is referred to with the exact Latin patronymic, "de Judicibus". Martino de Judicibus, initially assigned to the caravel Concepción, one of five ships of the Spanish fleet of Magellan, had embarked on the expedition with the rank of captain.
