The unique Knife figured at page 101 and two masks incrusted with a similar mosaic work (of turquoise and obsidian) are in Mr.Christy's collection; and a mask and head of similar workmanship are in the collection at Copenhagen.

These are the only known examples of this advanced style of Aztec art.
The whole once belonged probably to one set, brought to Europe soon after the Conquest of Mexico.

The two at Copenhagen were obtained at a convent in Rome; and, of the other three, two were for a long period in a collection at Florence, and the other was obtained at Bruges, where it was most probably brought by the Spaniards during their rule in the Low Countries..
