didn't get very far. Venturing ashore at one point along the river bank, Afonso tried to kidnap two Wolof children from a woodsman's hut. But he ran into their father, who proceeded to chase the Portuguese back to their launch and gave them such a beating that the explorers gave up on going any further, and turned back to the waiting caravels. Sometime between 1448 and 1455, the Portuguese captain Lourenço Dias opened regular trade contact on the Senegal River, with the Wolof statelets of Waalo (near the mouth of the Senegal River) and Cayor (a little below that), drumming up a profitable business exchanging Mediterranean goods (notably, horses) for gold and slaves. Chronicler Gomes Eanes de Zurara, writing in 1453, still called it the "Nile River", but Alvise Cadamosto, writing in the 1460s, was already calling it the "Senega" , and it is denoted as Rio do Çanagà on most subsequent Portuguese maps of the age. Cadamosto relates the legend that both the Senegal and the Egyptian Nile were branches of the Biblical Gihon River that stems from the Garden of Eden and flows through Ethiopia. He also notes that the Senegal was called "the Niger" by the ancients - probably a reference to Ptolemy's legendary 'Nigir' (Νιγειρ) (below the Gir), which would be later identified by Leo Africanus with the modern Niger River. Much the same story is repeated by Marmol in 1573, with the additional note that both the Senegal River and Gambia River were tributaries of the Niger River. However, the contemporary African atlas of Venetian cartographer Livio Sanuto, published in 1588, sketches the Senegal, the Niger and the Gambia as three separate, parallel rivers. Portuguese chronicler João de Barros (writing in 1552) says the river's original local Wolof name was Ovedech (which according to one source, comes from "vi-dekh", Wolof for "this river"). His contemporary, Damião de Góis (1567) records it as Sonedech (from "sunu dekh", Wolof for "our river"). Writing in 1573, the Spanish geographer Luis del Marmol Carvajal asserts that the Portuguese called it Zenega, the 'Zeneges' (Berber Zenaga) called it the Zenedec, the 'Gelofes' (Wolofs) call it Dengueh, the 'Tucorones' (Fula Toucouleur) called it Mayo, the 'Çaragoles' (Soninke Sarakole of Ngalam) called it Colle and further along (again, Marmol assuming Senegal was connected to the Niger), the people of Bagamo' (Bambara of Bamako?) called it Zimbala (Jimbala?) and the people of Timbuktu
