Mexican line of succession manuscript with original decorative silver and gilt binding and silver clasps. The text was signed three times by Viceroy Bucareli, Luna Gorraez y Malo, José Antonio Pedro Miguel Domingo de and incorporates relevant portions of older documents. Viceroy Antonio Bucareli y Ursua confirms Don José Antonio Pedro Miguel Domingo de Luna Gorraez y Malo, the Mariscal de Castilla, in his claim to the title and position of aguacil mayor perpetuo of the Tribunal de Cuentas, a position the mariscal inherited upon the death of his father. The post in question became part of the entailed estate of the mariscal’s family during the reign of Viceroy Albuquerque, and the line of succession is detailed in these documents. Because of the entail, the mariscal presents himself, with appropriate background documents, in order to obtain recognition of his claim.Viceroy Bucareli signs three of these four documents, once in full, the other two times as “Bucareli,” and he affixes the viceregal paper-over-wax seal at the bottom of the main document. The initial page of this manuscript bears an expertly designed and executed baroque manuscript border/frame, accomplished in shades of grey ink. The text contained within it is a very good example of Mexican calligraphy of the era.
