Provenance
One José Antonio Vera Olvera found the parchment, by chance, enclosed in a manila envelope and lodged between the pages of a 19th century devotional work on sale in a second-hand book market, and from him it passed to the Guerra Vera family of Querétaro who revealed its existence to Fr. Escalada in 1995. On the occasion of the formal donation of the parchment to the Archbishop of México on 14 April 2002, the owners requested that it be known as the Codex Escalada in honour of Fr. Escalada's life-work researching the apparitions. Fr. Escalada died in October 2006.
