Context paragraphs:
Vettakkorumakan: Vettakkoru Makan (Malayalam: വേട്ടക്കൊരുമകന്‍ ) is a Hindu deity worshipped in parts of North Kerala and North-Western Tamil Nadu.  This deity is alternately referred as Kiratha-Sunu (son of Kirata) in Sanskrit.  Vettakkorumakan is believed to be the son of Lord Shiva by his consort Parvathi, born when he assumed the form of a Kirata (hunter) to deliver a weapon known as Pashupathasthra to Arjuna.  He is mostly and exclusively worshipped in Malabar region of Kerala.  The most famous temple of this deity is the Balussery-Kotta Vettakkorumakan temple about 25 km from Calicut.  This was once the fort of the Rajas of Kurumbranad.  Other prominent temples are at Ramanthali, Nileshwar, Kottakkal, Nilambur, Karaparamba and various places in Kannur district and Kasargod district.  He is the family deity of the Rajas of Chirakkal, Nileshwar, Kottakkal, Nilambur Kovilakam, Kalathil Kartha's, Aluva, Amarambalam Kovilakam and Randu Illam Vargam Nambiars.  Those families among the erstwhile nobility of Malabar who have Vettakkorumakan as their family deity are connected in one way or other incidentally to either Balussery Fort or Kurumbranad.

Ancient Greek eros: Ancient Greeks used the word eros (Greek: ἔρως ) to refer to different aspects of love.  This diverse range of meanings is expressed by the plurality of Greek words for "Love", reflecting the versatility and complexity of eros.  The term was used to describe not only the affectionate marital relationship between a man and a woman but also the institution of pedagogic "pederastic" relations (Eros paidikos, παιδικός ἔρως), solemnized in certain Greek poleis.  Such was the importance of eros for the ancient Greeks that the god of love, also named Eros, was held in Hesiod's cosmogony to be the primordial deity, the first god, older than all the others.

Dolos (mythology): In Greek mythology, Dolos or Dolus ("Deception") is the spirit of trickery and guile.  He is also a master at cunning deception, craftiness, and treachery.  He was the son of Gaia (Earth)) and Aether (Hyginus, "Fabulae" Theogony 3) or Erebus and Nyx (Cicero, "De Natura Deorum" 3.17).

Erebus: In Greek mythology, Erebus , also Erebos (Greek: Ἔρεβος , "deep darkness, shadow"), was often conceived as a primordial deity, representing the personification of darkness; for instance, Hesiod's "Theogony" identifies him as one of the first five beings in existence, born of Chaos.  Erebus features little in Greek mythological tradition and literature, but is said to have fathered several other deities with Nyx; depending on the source of the mythology, this union includes Aether, Hemera, the Hesperides, Hypnos, the Moirai, Geras, Styx, Charon, and Thanatos.

Kayra: Kayra or Kaira, (Altai: Кайракан; Kyrgyz: Кайра ; Turkish: "Kayra Han" ; Azerbaijani: "Kayra Xan" ; Ottoman Turkish: كايرا‎ ) is the Spirit of God and creator god in Turkic mythology.  He is the supreme god of the Tatars and the Son of the sky deity (Gök Tengri).  This son, Kara Han (the black king), left his father's home in the heaven and went to live in the underworld.  On occasion, identified as Kara-Khan (black king), he was the primordial god and his father was the ancordial god called Tengri.

Aether (mythology): Aether or Aither ("Æthere", Ancient Greek: Αἰθήρ , ] ), in ancient Greece, was one of the primordial deities.  Aether is the personification of the upper air.  He embodies the pure upper air that the gods breathe, as opposed to the normal air (ἀήρ, "aer") breathed by mortals.  Like Tartarus and Erebus, Aether may have had shrines in ancient Greece, but he had no temples and is unlikely to have had a cult.

Awal: Awal (Arabic: أوال‎ ‎ ) is an ancient name of Bahrain, an island country in the Persian Gulf.  The name Awal had remained in use, probably for eight centuries.  Awal was derived from the name of a god that used to be worshiped by the inhabitants of the islands before the advent of Islam.  Awal resembled the head of an ox.  As for the meaning of this name, there are "ʼawwal" 'first, first part, previous'; "ʼawwalan" 'firstly, at first'; "ʼawwalī" 'prime, primordial, original'.  Awal Premi also means 'the best' in many Indian languages.  Similarly the deity Awal of Bahrain appears to be very similar to the deity Nandi of the Hindus.  The Indus valley civilization also had a deity like an ox.  It is suggested that there were religious and cultural links between these cultures.

Devol (deity): Devol (also spelled as Dewol) is a deity subjected to worship and belief in Sri Lanka.  He is one of the twelve deities worshiped in Sri Lanka as "Dolos Deviyo" (twelve gods), who are believed to be intervening in the affairs of the worldlings.

Vegetation deity: A vegetation deity is a nature deity whose disappearance and reappearance, or life, death and rebirth, embodies the growth cycle of plants.  In nature worship, the deity can be a god or goddess with the ability to regenerate itself.  A vegetation deity is often a fertility deity.  The deity typically undergoes dismemberment (see "sparagmos"), scattering, and reintegration, as narrated in a myth or reenacted by a religious ritual.  The cyclical pattern is given theological significance on themes such as immortality, resurrection, and reincarnation.  Vegetation myths have structural resemblances to certain creation myths in which parts of a primordial being's body generate aspects of the cosmos, such as the Norse myth of Ymir.

Zurvanism: Zurvanism is an extinct heretical branch of Zoroastrianism in which the divinity Zurvan is a First Principle (primordial creator deity) who engendered equal-but-opposite twins, Ahura Mazda and Angra Mainyu.  Zurvanism is also known as "Zurvanite Zoroastrianism", and may be contrasted with Mazdaism, which is the surviving form of Zoroastrianism and in which Ahura Mazda and Angra Mainyu are either themselves primordial (the traditional view), or the 19th/20th century developments in which Ahura Mazda is no longer the Creator of only the good, but also perceived as the origin of Angra Mainyu.
