In this article Colini (pp. 324-325) describes two masks and an idol in the Museo Borgiano in Rome. Regarding these specimens he quotes from Vitæ Synopsis Stephani Borgiæ, S. R. E. Cardinalis amplissimi, S. Congr. de Propaganda Fide Præfecti, Roma, 1805, p. 44, “Classis mexicana: multa lignea et testacea idolorum simulacra forma et figura singulari, ac gente mexicanæ propia.” He describes the idol as being made of wood in the form of a human figure, 45 cm. high. The two masks of wood are described, and figured on the plate containing drawings of other American antiquities. It is highly probable that these three objects were formerly decorated with mosaic.
