The contrast between the two buildings could not be more eloquent. The Feathered Serpent Temple is the most profusely decorated building at Teotihuacan: hundreds of heads in relief, undulating serpents, shells, and conch forms covering every facade. The Attached Platform that covers it is its exact opposite: four smooth tiers, painted red, without a single sculptural element. Covering one building with another can be understood as an act of renewal. That moment, around 350 CE, coincides with one of the most profound shifts in the city's iconography: the beginning of a more impersonal and collective visual program.
