This work is a compendium of ceremonial oaths for the University of Mexico faculty upon assuming office, and for students during graduation ceremonies. Printed in large, clear type, the spacious leading between the lines may have been designed for easy reading by persons taking the appropriate oaths. Founded in 1551 as the Real y Pontificia Universidad de México by a decree of Charles I, the institution survived political turmoil and several closures, finally regrouping and evolving from an ecclesiastically controlled institution into the modern Universidad Nacional Autónoma de México.
"The work was written by Dr. Manuel Ignacio Beye de Cisneros y Quijano (1718-1787) during a period of reform of the University. The author built up the library to more than 10,000 volumes, endowed libraries in Mexico, founded the Colegio de Abogados, and he was considered an important priest. He was born in Mexico, the son of Francisco Beye de Cisneros and Francisca Quijano de Alcocer. For more on the author, see: John E. Kicza, “The Great Families of Mexico: Elite Maintenance and Business Practices in Late Colonial Mexico” in The Hispanic American Historical Review, Vol. 62, No. 3 (Aug., 1982), pp. 429-457.

"The press of the Biblioteca Mexicana, one of the most important of eighteenth-century Mexican publishing concerns, was founded, owned, and operated in his own house, by the wealthy and learned don Juan José de Eguiara y Eguren, canon of Mexico Cathedral, who, with his brother Manuel, had ordered a printing press from Madrid in 1744 or possibly 1754, according to Medina. The press began operating in the latter year, ‘en frente de San Agustín’ and from the start was a great success. Such was Eguiara’s enthusiasm for his hobby, that he refused the bishopric of Yucatán in order to devote himself to typography. In 1761, the press was moved to a site next to the Church of the Capuchin nuns, whose confessor Eguiara was. In 1763 Eguiara died, and after four years of uncertain proprietorship, the concern was acquired by José de Jáuregui, although the original name was preserved until at least 1774, and appears occasionally even afterwards. Some 356 titles for the period 1754-1774 are listed by José Toribio Medina in his monumental La Imprenta en México..., and of this number, about 264 were issued during Eguiara’s ownership of the press."(Whitehead, “An Eighteenth-Century Mexican Book” in The British Museum Quarterly, Vol. 22, Nos. 1/2 (1960), pp. 8-10).
