In Brazil, where Christopher Columbus is not well known, 12 October is a federal holiday in honour of children, as well as an important day in the Brazilian Catholic religious calendar, with a pilgrimage in São Paulo to the sanctuary of Nossa Senhora da Conceição Aparecida. The statue was supposedly discovered in a river in São Paulo’s interior by three fishermen in 1717, who were blessed by abundant catches thereafter. Though she started out white, the river turned her black; or perhaps it was the smoke from the fishermen’s votive candles. In any event, she is a powerful symbol of liberty for the Afro-descended majority, in a country where slavery formally ended only in 1888.
