 It is believed that the original owner of the manuscript was Luis Pérez Dasmariñas, son of Governor General Gómez Pérez Dasmariñas, who was killed in 1593 by "Sangleys" or Chinese living in the Philippines.Luis succeeded his father in office as Governor-General of the Philippines.Since Spanish colonial governors were required to submit written reports on the territories they governed, it is likely that the manuscript was written under the orders of the governor.
