The elaborate series of pictures of the various crafts in the Florentine manuscript of Sahagun (laminas liv to lxiv) includes those that show in detail the work of the goldsmiths and the feather-workers; but the illustrations devoted to the lapidaries we are unable to correlate, in the absence of the text, with the Nahuatl text of the Sahagun manuscript in the Real Academia de la Historia in Madrid, which we will give later from the study by Dr. Seler containing a translation of the native text into French. This description of the work of the lapidaries informs us only concerning the working and polishing of the stones. Unlike the other accounts by Sahagun regarding the goldsmiths and the feather-workers, which enlighten us with respect to the details of these two fine arts, he does not here enter into any description concerning the delicate work of the artists who fashioned the beautiful pieces of stone mosaic. Although such work was turned out by the Aztecan workmen, as we have already demonstrated, it seems highly probable that in times immediately preceding the Spanish conquest, the Aztecan kings Ahuitzotl and Montezuma obtained a considerable number of such objects through tribute and by barter with the tribes living in what are now the states of Vera Cruz, Oaxaca, and western Chiapas. As our knowledge of Mexican archeology, now all too meager, is extended, it is very probable that we will find vestiges of this art in the Pacific state of Guerrero, where great numbers of jadeite and other greenstone objects have been discovered, with a respectable number of specimens indicating the high artistic skill of the indigenes of that section. We may also hope to find relics of this art in the area of Matlaltzincan culture to the north of the valley of Mexico, and also in the field of Tarascan culture in the states of Michoacan and Jalisco, for, as will be related, mosaic specimens have been recovered from ancient ruins as far north as the State of Zacatecas.

II) of the work of the lapidaries we herewith append, with the Nahuatl text and a translation of the French rendering by Seler.[38] 1. _In tlateque tulteca ynic quitequi yn yztac tehuilotl yoan tlapaltehuilotl yoan chalchiuitl yoan quetzalitztli ynica teoxalli yoan tlaquauac tepuztli._ 1. The lapidary artisans cut rock-crystal, amethyst, emerald, both common and precious, by means of emery and with an instrument of tempered copper: 2. _Auh ynic quichiqui tecpatl tlatetzotzontli._ 2. And they scraped it by means of cutting flint. 3. _Auh ynic quicoyonia ynic quimamali teputztlacopintli._ 3. And they dug it out (hollowed) and drilled it by means of a little tube of copper. 4. _Niman yhuian quixteca quipetlaua quitemetzhuia, auh yn yc quicencaua._
