In this way, he walked 1000 km to the South (an easy direction to identify, since the North is indicated on the map), leaving Cear\u00e1 and passing through Pernambuco and Bahia. In this state, he changed course and traveled 1,000 km to the West, arriving in Goi\u00e1s, from where he headed another 750 km to the South, arriving in the state of S\u00e3o Paulo. On this route, the traveler saw the ecosystems of the Caatinga, the Cerrado and the Atlantic Forest.<\/p>\n
