Leaving aside Sancho de Elso's catechism (1561), the text of which has not survived the oldest Basque catechism is the one by Betolatza, Doctrina Christiana en Romance y Bascuence, published in Bilbao in 1596.
We had no data about the author of this booklet. The purpose of this paper is to show that he was born at Betolatza (province of Alava) and that he was priest in his birth-place and in the cathedral of Santo Domingo de la Calzada, the town where he died between autumn 1599 and spring 1600.
A copy of Betolatza's catechism has recently been bought by the Libray of Basque Parliement. Undoubtedly, this copy, the only one whose existence we know, is the same as the one Azkue photographed in the thirties.
