Spanish painter, son of Salvador Castelló, an Aragonian painter who settled in Valencia in 1685. He began working at an early age with Francisco Ribalta, one of whose daughters he married in 1610. In 1616 he appears in the register of the Colegio de Pintores in Valencia, and, probably in 1618, he settled in the Segorbe district together with Juan Ribalta and Abdón Castaneda (c. 1580-1629). There they worked in the Carthusian monastery of Valdecristo, where Castelló painted the Apotheosis of St Bruno (Castellón, Museo Provincial de Bellas Artes), and in the Augustine monastery of S Martín, where he painted the altarpiece representing the Descent into Limbo (in situ). Between 1622 and 1626 he collaborated with the same team on the altarpiece for the parish church of the Asunción at Andilla (Valencia province) with paintings of the Birth of the Virgin and Christ among the Doctors (in situ). In 1628 he was the executor of Juan Ribalta's will. After the death of the Ribaltas, he is documented again in Segorbe (1630), in competition with Pedro García Ferrer (1583-1660), to paint the Massacre of the Innocents (untraced). The last record of Castelló is in Segorbe in 1635. //
