В 1502 г. на карте появилось название Рио-де-Жанейро

The expedition of the Portuguese navigator Gaspar de Lemos discovered a bay on the Atlantic coast of Brazil, which the local Indians called Guanabara. The Portuguese thought it was the delta of some unknown but large river and without much thinking called it the River of January – in their native language, of course. Then the mistake was identified, but the sonorous name did not disappear: half a century later, a city was founded on the shores of the bay. It inherited the name of the alleged river – Rio de Janeiro.
