Aymeric Picaud

Aymeric Picaud was a 12th-century French scholar, monk and pilgrim from Parthenay-le-Vieux in Poitou. He is most widely known today as being the suspected author of the Codex Calixtinus, an illuminated manuscript giving background information for pilgrims travelling the Way of St. James. In essence, he wrote one of the earliest known tourist guidebooks. Provided by Wikipedia
