Galego and Cabano, two dark-haired oxen, pulled the sacred image of Our Lady of Remedies on a procession float for more than two hours through this small town in Portugal’s wine country. “I love to work with animals, and I have a lot of faith in Nossa Senhora dos Remédios,” said Antonio Faustino, who guided the massive animals in the celebration of this particular image of the Virgin Mary, venerated here since the 1500s. Lamego’s festival, nicknamed “Portugal’s pilgrimage,” is one of the oldest and largest of the many religious feasts that throughout summer draw tens of thousands of people to hamlets and metropolises.
