144 meters while north–south remained the same. This building was constructed to contain Burials 5 and 4 in approximately 350 CE. Building 7 is the final structure, which is still visible today, but was built in about 400 CE. A distinct shift in architectural style between the first three buildings may be indicative of an ideological shift. Function Ritual sacrifice This pyramid had several religious functions. The main function of the pyramid was public ritual sacrifice. Archaeologists have found a great number of sacrificed remains in the foundations of the pyramid. Among the sacrificial victims were felines, birds of prey, snakes, humans, and more. These sacrifices can be carefully cataloged and examined when looking at the different burials within the different layers of buildings. Thus far, archaeologists have found a total of 5 rectangular burial offering complexes within the 7 layers of the pyramid. Sacrificial and inanimate offerings were carefully selected to represent large ideas of Teotihuacan cosmology (such as authority, militarism, human and animal sacrifice, femininity) rather than the worship of a single ruler or deity. Burials Within the seven layers that make up the Pyramid of the Moon, there are five burial complexes labeled two through six. They were found to have contained sacrificial victims and other remains such as figurines, obsidian objects, as well as nonhuman animal remains. While the pyramid structures are labeled from the earliest to the oldest (one through seven), the burial structures are numbered in the order in which they were found (two through six). For example, burial two and six are associated with the time of the fourth structure, three with the fifth structure, and four and five with the sixth structure. It is important to note that there have been no associated burials within structures one through three. The burials begin in conjunction with structure four. Due to this, Siguyama suggests a large-scale change politically and militaristically within Teotihuacan during the period of which structure four was built. This is because of the substantial increase in size of structure four, as well as the addition of ritualistic burials that correlate to the addition of new structures to the Pyramid of the Moon. Burial two was built during the construction of Building four and was believed to be built around 250 AD. It contained a single-seated corpse of a man facing west who was probably around 40–50 years of age. The structure
