Father Chirino wrote Relacion de las Islas Filipinas, which he later transformed into a longer and more detailed account of Jesuit work in the Philippines. His work is the first history, not just of the Jesuit missions, but also of the Catholic missions in the Philippines and served as the source for later histories. For one reason or another, this history was never published and remained in manuscript form, until the historian Jaume Gorriz i Abella edited it with copious notes. This is the history now presented, albeit without the notes, in an English translation.
