This summary of Hemández’s very extensive manuscript account of the natural history of Mexico (see No. 1820.1) was edited by N.A. de Recchi, and published at the expense of Prince Federico Cesi (1585-1630), with notes by Giovanni Terrentio (1575-1630), Johannes Faber (1574-1629) Fabio Colonna (1567-1650) and Cesi. Publication of the work was discontinued with the death of Cesi in 1628. It is usually seen in the reissue of 450 copies in 1648/49 or 1651, for which Francesco Stelluti was responsible. The remainder of Hemandez’s extant manuscripts were finally published in the Obras completas, 4 vols., Mexico City, 1959-66. See Nos. 1819-1 & 1820.1.
