JOSEPH DE ACOSTA. "Historia natural y moral de Indias," Sevilla, 1590. I merely mention this author, without entering into further bibliographical details about his work. It has been translated into many languages, and--in part or wholly--incorporated in many general collections of "Americana." He says but little about Yucatan, still his book is indispensable to any one studying Yucatecan antiquities. I also advert here to his former publication, which is but little known: "De promulgatione Evangelii apud Barbaros, sive de procuranda Indorum salute," Libros 6; printed in 1589. GERÓNIMO DE MENDIETA. "Historia ecclesiástica Indiana," written about 1590, but printed for the first time, by Sr. J. G. Icazbalceta, at Mexico, in 1870--Contains much and valuable information.--Mendieta has been extensively copied by Torquemada. FRAY TORIBIO DE PAREDES, SURNAMED "MOTOLINIA." "Historia de los Indios de Nueva-España," written about 1540, but published in full only by Sr. Icazbalceta in Vol. I. of "Coleccion de Documentos, &c."--Mentions Yucatan incidentally.--A large part of the work had been printed before in the "Documentos inéditos, &c." under the title of "Ritos Antiguos, Sacrificios é Idolatrias de las Indias de la Nueva-España,"--also in Vol. IX. of Lord Kingsborough.--A Latin version, under the title of "De Moribus Indorum" may have existed once. * * * * * Yucatan is, furthermore, mentioned in many works of a more general character, embodying information gathered mostly from the sources already referred to. I do not, therefore, enter into any lengthy bibliographical sketches of them. SIMON GRYNAEUS. "Novus Orbis," 1532. Already noticed under Petrus Martyr. PETRUS APIANUS. "Cosmographia," 1539, 1545, 1561 (Dutch version), &c. ABRAHAM ORTELIUS. "Theatrum orbis terrarum," 1571, 1588, &c. THOMASO PORCACCHI. "L'isole pio famose del Mondo," 1572, 1576, 1590, &c., &c. G. MERCATOR. "Atlas, six Cosmographical Meditations." Duisburg, 1594. CONRAD LOEW. "Meer oder See-Ansicht Buch." Cologne, 1598. SEBASTIAN MUNSTER. "Cosmographey," 1575, &c. ANDRÉ THEVET. "Les singularites de la France antarctique, autrement nommé Amérique, et de plusieurs Terres et Isles decouvertes de notre temps."--Paris, 1558; Antwerp, 1558; in Italian, at Venice, 1561. I forbear further mention of the polemic works on the origin of the American Indians,--and now turn to some writers whose works are probably lost, or at least not accessible, although there is positive evidence of their former existence. FRAY GERÓNIMO ROMAN. "Republica Indiana"--certainly existed as late as 1630, or "República de las Indias Occidentales." FRAY ALONZO SOLANA. "Noticias Sagradas y profanas de las Antigüedades y Conversion de los Indios de Yucatan." (Written before 1600). DON FRANCISCO MONTEJO. "Carta al Rey sobre la fundacion de la Villa de San Francisco de Campeche, y de la Ciudad de Mérida," 14 June, 1543. (Still at Sevilla, leg. 7. "Cartas de Indias").
