For example, the manuscript of Fray Juan de Oliver’s Declaración de la doctrina christiana en idioma tagalog pictured above from the 1590s can be found in the deceptively nondescript Lot 527 in the Lilly Library of Indiana University. Oliver’s translation of the Christian Doctrine mostly consisted of catechetical explanations in Tagalog about some common prayers of the Catholic Church, such as this explanation on the opening page about the Sign of the Cross.
