Commentary by Pavez Ojeda: “Urreta, Padre Luys 1610 – Historia eclesiástica, política, natural y moral de los grandes y remotos reynos de la Etiopía, monarchia del emperador llamado Preste Juan de las Indias – Valencia: P.P. Mey, 731 p. There is a French edition: Histoire des Freres Precheurs en Ethiopie. Dominican friar Urreta’s book is known to have been written under the influence of Juan Baltazar Abisinio. However, there is no agreement on the origin of Urreta’s information: if he had possibly traveled to Ethiopia or if he had only gathered histories of the Abyssinian brothers who arrived to Spain and the Vatican.” (Pavez Ojeda 2006a, 758)
