found on the sculptures of Central America and in the Dresden Codex. So is the general character of the architecture and sculpture, as any one may see at a glance.
It is quite true that the so-called Aztec Astronomical Calendar was in use in Central America, and that many of the religious observances in both countries, such as the method of sacrificing the human victims, and the practice of the worshippers drawing blood from themselves in honour of the gods, are identical. But there were several ways in which this might have been brought about, and it is no real proof that the civilization of either country was an offshoot from that of the other. To consider it as such would be like arguing that the negroes of Cuba and the Indians of Yucatan had derived their civilization one from the other, because both peoples are Roman Catholics, and use the same almanac. On the whole I am disposed to conclude that the civilizations of Mexico and Central America were originally independent, but that they came much into contact, and thus modified one another to no small extent.
