As Nicolás Rodríguez Franco, the printer of the second edition, informed his readers in his "Proemio", few exemplars of the first edition survive because the greater part of the print-run was lost in a shipwreck, and only three copies were known to him. Eight copies of the first edition exist in various libraries in North America and Europe, two of which lack the original frontispiece, and the other six of which lack also the first 32 pages. A ninth copy exists in Mexico divided between one owner who possesses the first volume, and another who possesses the other two.
