Patron god in the context of "Quetzalcoatl"

Neptune (Latin: Neptūnus [nɛpˈtuːnʊs]) is the god of freshwater and the sea in the Roman religion. He is the counterpart of the Greek god Poseidon. In the Greek-inspired tradition, he is a brother of Jupiter and Pluto, with whom he presides over the realms of heaven, the earthly world (including the underworld), and the seas. Salacia is his wife.

Depictions of Neptune in Roman mosaics, especially those in North Africa, were influenced by Hellenistic conventions. He was likely associated with freshwater springs before the sea; his festival, Neptunalia, took place on July 23, during the peak of summer when water was scarcest. Like Poseidon, he was also worshipped by the Romans as a god of horses, Neptunus equestris, who was also a patron of horse-racing.

The altepetl (Classical Nahuatl: āltepētl [aːɬ.ˈte.peːt͡ɬ] , plural altepeme or altepemeh [aːɬ.ˈte.ˈpeːme(h)]) was the local, ethnically-based political entity, usually translated into English as "city-state", of pre-Columbian Nahuatl-speaking societies in the Americas. The altepetl was composed of smaller units known as calpolli and was typically led by a single dynastic ruler known as a tlatoani, although examples of shared rule between up to five rulers are known. Each altepetl had its own jurisdiction, origin story, and served as the center of Indigenous identity. Residents referred to themselves by the name of their altepetl rather than, for instance, as "Mexicas". "Altepetl" was a polyvalent term rooting the social and political order in the creative powers of a sacred mountain that contained the ancestors, seeds and life-giving forces of the community. The word is a combination of the Nahuatl words ātl (meaning "water") and tepētl (meaning "mountain"). A characteristic Nahua mode was to imagine the totality of the people of a region or of the world as a collection of altepetl units and to speak of them on those terms. The concept is comparable to Maya cah and Mixtec ñuu. Altepeme formed a vast complex network which predated and outlasted larger empires, such as the Aztec and Tarascan state.

Established altepeme were characterized by a central temple dedicated to a patron god particular to the identity of the altepetl and a central market. Altepeme were typically multiethnic and communal cohesion was often maintained through territorial exclusiveness.

Huitzilopochtli (Classical Nahuatl: Huītzilōpōchtli, IPA: [wiːt͡siloːˈpoːt͡ʃt͡ɬi] ) is the solar and war deity of sacrifice in Aztec religion. He was also the patron god of the Aztecs and their capital city, Tenochtitlan. He wielded Xiuhcoatl, the fire serpent, as a weapon, thus also associating Huitzilopochtli with fire.

The Spaniards recorded the deity's name as Huichilobos. During their discovery and conquest of the Aztec Empire, they wrote that human sacrifice was common in worship ceremonies. These took place frequently throughout the region. When performed, typically multiple victims were sacrificed per day at any one of the numerous temples.
