SCOPE OF THE PRESENT INVESTIGATION. 39 
This same event, as depicted in the Codex Telleriano-Remensis,! is given 
in figure 1,d. Here we see the year 10 Tochtli at the top and to the left a 
warrior with shield and arrows on his left arm, signifying conquest. A com- 
parison of this shield with the one in figure 1, c, shows that the two are prac- 
tically identical. Below is the sign for Tecuantepec. In this passage the 
idea of conquest is brought out by the warrior, shield, and arrows, the burn- 
ing house having been omitted. 
Finally, this same event, as represented in the Codex Vaticanus 3738,7 is 
shown in figure 1,¢. The warrior with a shield on his left arm, standing 
above a jaguar’s head, which rests on top of a hill, is substantially the same 
as in figure 1,d. To the right is the year 
10 Tochtli, and the whole passage records 
the conquest of Tecuantepec in that year 
by the Aztec. 
In figure 2, from the Codex Telle- 
riano-Remensis,’ is shown the first human 
sacrifice, which was celebrated at Tenoch- 
titlan (the City of Mexico), in the year 5 
Tecpatl (1484 a. p.) on the occasion of 
the dedication of the great teocalli (Na- 
huatl for house of the god) or Temple of 
Huitzilipochtli, the Aztec God of War. Fic. 2.—Dedication of the great teocalli

Human blood streams down the double stairway and stains the balustrades 
at the top. To the right is the officiating priest in the act of sacrifice. The 
victim, in a welter of blood (red in the original manuscript), lies stretched on 
his back with his eyes closed, as though the sacrifice had already been 
consummated. 
In addition to such purely historical matters as the above, record of 
unusual natural phenomena was also carefully kept, as shown in the several 
examples in figure 3, all from the Codex Telleriano-Remensis. 
The day-sign Ollin in Nahuatl means “‘movement,” and this character was 
used in the Aztec manuscripts to express earthquakes. In figure 3, a, is shown 
an earthquake which occurred in the year 7 Tecpatl (1460 a. p.).4 Figure 
3, b, and c, shows that earthquakes occurred in the years 2 Acatl (1507.4.p.)° 
and 2 Calli (1533 a. D.)® respectively. 
In the former year an eclipse of the sun is also noted, shown graphically 
in figure 3,b, by the missing sector inthe sun-sign. In figure 3,c, there is also 
recorded a volcanic eruption, possibly of Popocatepetl (Nahuatl for smoking
