Kukulkan (/kuːkuːlˈkän/ ) (""Plumed Serpent"", ""Feathered Serpent"") is the name of a Maya snake deity that also serves to designate historical persons.
 The depiction of the Feathered Serpent is present in other cultures of Mesoamerica.
 Kukulkan is closely related to the deity Q'uq'umatz of the K'iche' people and to Quetzalcoatl of Aztec mythology.
 Little is known of the mythology of this Pre-Columbian era deity.
Quetzalcoatl ( ; ] ) (,    ) forms part of Mesoamerican literature and is a deity whose name comes from the Nahuatl language and means "feathered serpent".
 The worship of a feathered serpent is first documented in Teotihuacan in the first century BC or first century AD.
 That period lies within the Late Preclassic to Early Classic period (400 BC – 600 AD) of Mesoamerican chronology, and veneration of the figure appears to have spread throughout Mesoamerica by the Late Classic period (600–900 AD).
"For other meanings of this word, see Acolnahuacatl (deity), an Aztec god also known as Acolmiztli.
 Nezahualcoyotl, a ruler of Texcoco had the second name Acolmiztli."
Q'uq'umatz (] ) (alternatively Qucumatz, Gukumatz, Gucumatz, Gugumatz, Kucumatz etc.) was a deity of the Postclassic K'iche' Maya.
 Q'uq'umatz was the Feathered Serpent divinity of the "Popol Vuh" who created humanity together with the god Tepeu.
 Q'uq'umatz is considered to be the rough equivalent of the Aztec god Quetzalcoatl, and also of Kukulkan of the Yucatec Maya tradition.
 It is likely that the feathered serpent deity was borrowed from one of these two peoples and blended with other deities to provide the god Q'uq'umatz that the K'iche' worshipped.
 Q'uq'umatz may have had his origin in the Valley of Mexico; some scholars have equated the deity with the Aztec deity Ehecatl-Quetzalcoatl, who was also a creator god.
 Q'uq'umatz may originally have been the same god as Tohil, the K'iche' sun god who also had attributes of the feathered serpent, but they later diverged and each deity came to have a separate priesthood.
Tepeu is a word of the K'iche' Maya language meaning "sovereign" (also "one who conquers" or "one who is victorious").
 The title is associated with the god Q'uq'umatz of the K'iche'-Maya, one of the creation gods of the Popol Vuh; his whole name translating as "Sovereign Plumed Serpent".
 The title has also been used by numerous K'iche' rulers such as Tepepul.
Mixcoatl (Nahuatl: "Mixcōhuātl" , ] from mixtli ] "cloud" and cōātl ] "serpent"), or Camaztle ] from camaz "deer sandal" and atle "without".
, or Camaxtli, was the god of the hunt and identified with the Milky Way, the stars, and the heavens in several Mesoamerican cultures.
 He was the patron deity of the Otomi, the Chichimecs, and several groups that claimed descent from the Chichimecs.
 While Mixcoatl was part of the Aztec pantheon, his role was less important than Huitzilopochtli, who was their central deity.
 Under the name of Camaxtli, Mixcoatl was worshipped as the central deity of Huejotzingo and Tlaxcala.
The Feathered Serpent was a prominent supernatural entity or deity, found in many Mesoamerican religions.
 It was called Quetzalcoatl among the Aztecs, Kukulkan among the Yucatec Maya, and Q'uq'umatz and Tohil among the K'iche' Maya.
 The double symbolism used in its name is considered allegoric to the dual nature of the deity, where being feathered represents its divine nature or ability to fly to reach the skies and being a serpent represents its human nature or ability to creep on the ground among other animals of the Earth, a dualism very common in Mesoamerican deities.
In the Aztec religion, Huitzilopochtli (,    ), is a Mesoamerican deity of war, sun, human sacrifice and the patron of the city of Tenochtitlan.
 He was also the national god of the Mexicas, also known as Aztecs, of Tenochtitlan.
 Many in the pantheon of deities of the Aztecs were inclined to have a fondness for a particular aspect of warfare.
 However, Huitzilopochtli was known as the primary god of war in ancient Mexico.
 Since he was the patron god of the Mexica, he was credited with both the victories and defeats that the Mexica people had on the battlefield.
 The people had to make sacrifices to him to protect the Aztec from infinite night.
 It is important to remember that the defeat of their patron deity meant the defeat of his people.
 This is one of the many reasons why they were concerned with providing exquisite tribute and food for him.
 Not only was it important for him to survive his battles, but the fate of the Mexican people would have rested in the victory of Huitzilopochtli.
 He wielded Xiuhcoatl as a weapon, associating him with fire.
Tlaxochimaco is the name of the ninth Month of the Aztec calendar.
 It is also a festival in the Aztec religion, dedicated to the Aztec God of War Huitzilopochtli.
 It is called the Bestowal or Birth of Flowers.
The Temple of the Feathered Serpent is the modern-day name for the third largest pyramid at Teotihuacan, a pre-Columbian site in central Mexico (the term Teotihuacan (or Teotihuacano) is also used for the whole civilization and cultural complex associated with the site).
 This structure is notable partly due to the discovery in the 1980s of more than a hundred possibly sacrificial victims found buried beneath the structure.
 The burials, like the structure, are dated to between 150 and 200 CE.
 The pyramid takes its name from representations of the Mesoamerican "feathered serpent" deity which covered its sides.
 These are some of the earliest-known representations of the feathered serpent, often identified with the much-later Aztec god Quetzalcoatl.
 The structure is also known as the Temple of Quetzalcoatl, and the Feathered Serpent Pyramid.
