 Tlalocan has also been recognized in certain wall paintings of the much earlier Teotihuacan culture.Among modern Nahua-speaking peoples of the Gulf Coast, Tlalocan survives as an all-encompassing concept embracing the subterranean world and its denizens.In the Florentine Codex, a set of sixteenth-century volumes which form one of the prime sources of information about the beliefs and history of Postclassic central Mexico, Tlalocan is depicted as a realm of unending Springtime, with an abundance of green foliage and edible plants of the region.
