"Memoria relativa á las ruinas de Nachán, en las inmediaciones del pueblo de Santo Domingo del Palenque." MS. formerly belonged to Brasseur de Bourbourg. It was written about 1784, and is the first authentic report on the celebrated ruins.

Documents relative to the explorations of Palenque.
Besides the "Memoria" of Ordoñez already quoted, which first directed attention to the ruined pueblo, there exist the following documents:
José de Estacheria. "Expediente sobre el descubrimiento de una gran Ciudad en la provincia de Chiapas, distrito de Guatemala." 28 Nov. 1784. (Archives of the royal Academy, at Madrid).—It is directed to the lieutenant "Alcalde mayor" of Chiapas, at Sto Domingo del Palenque, directing him to survey the ruins.
Josef Antonio Calderon. "Informe, fecho en 15 de Diciembre de 1784." Description of the ruins. MSS. translated and published by Brasseur in "Ruines de Palenque," 1866.
Antonio Bernasconi. Other reports on the ruins, accompanied by plans and drawings. MS. in Spain. Date, 13 June, 1578.
Juan Bautista Muñoz. Letter to the Marquis de Sonora, written 1786. Translated by Brasseur: "Ruines de Palenque." 1866.
Antonio del Rio. "Descripcion del terreno y poblacion antigua nuevamente descubierta en las inmediaciones del pueblo del Palenque."—I have already referred to it under "Yucatan." Whether the plates of the English edition are genuine, is yet doubtful.
