Christopher Columbus, the first European to reach the island, named it after St. Vincent of Saragossa, whose feast day it was on the day Columbus first saw it (22 January 1498). The name of the Grenadines refers to the Spanish city of Granada, but to differentiate it from the island of the same name, the diminutive was used. Before the arrival of the Spaniards, the Carib natives who inhabited the island of St. Vincent called it Youloumain, in honour of Youlouca, the spirit of the rainbows, who they believed inhabited the island.
