Last week I bought a book on Argentina's mythical beings (Seres Mitológicos Argentinos) written by Adolfo Colombres. It is basically a dictionary with over five hundred entries, each one corresponding to a mythical entity. It is superbly illustrated by Luis Scafati.
The mythical creatures span several native cultures from north to south (Guaraní, Diaguita, Toba, Wichi, etc.) as well as some "westernized" ones which belong to Argentina's Creole mythology.
Yet I was unpleasantly surprised by the author's comment "We have not included the Yámanas because they are Chilean".
This is not true. The Yámana (also known as Yagan) lived in the territory that is now part of Argentina and also Chile. They were boat people and moved around in canoes that they made with the bark of the Nothofagus trees.
As the following map shows (the Yámana territory is marked in green), they clearly extended east along the Beagle Channel into Argentina.
Furthermore, the name of the capital city of the Argentine Province of Tierra del Fuego (Ushuaia) is a Yagan word! It was here that Rev. Thomas Bridges headed an Anglican mission among the Yagans between 1871 and 1886. He spoke their language fluently and even wrote a Yagan language dictionary.
His son, Lucas Bridges recorded interesting information about these people and the Bridges family, established at their estancia (Ranch) at Harberton, close to Ushuaia, assisted many of the later scientific expeditions sent to Tierra del Fuego to study the place and the native people.
This made me wonder why Colombres overlooked the abundant bibliography available on these now extinct Argentine natives and decided that they were Chilean.
It also raises the question of how deep has he researched the other contents of his book. My suggestion is to us this book as a very superficial introduction to Argentine native and popular myths, but go to the sources if you want deeper or reliable information.
