Gregory McIntosh claims that to the left of that dog-like animal, one can read the words Sano Saneyro, and that this technically qualifies as the first textual reference to Rio de Janeiro, which is, quite fittingly, next to a river.It is likely, however, that this is a mis-translation of janawereh sahej. The word janawereh is clearly visible, and one might surmise that this must indeed be Janeiro. However, where it is written: bu janawereh sahej dulul this is actually more plausibly translated as: “They call this beast sahej.” Thus, this legend cannot be “Sano Saneyro” and janawereh is nothing more than the word “beast.” Possibly the beast referred to is the Lobo Guará, a canid found only in South America and pictured in the map.
