According to ancient local tradition, on 2 January of the year AD 40, the Virgin Mary appeared to James on the bank of the Ebro River at Caesaraugusta, while he was preaching the Gospel in Spain. She supposedly appeared upon a pillar, Nuestra Señora del Pilar, and that pillar is conserved and venerated within the present Basilica of Our Lady of the Pillar, in Zaragoza, Spain. Following that apparition, St James returned to Judea, where he was beheaded by King Herod Agrippa I in the year 44.
