The Vainakh people of the North Caucasus (Chechens and Ingush) were Islamised comparatively late, during the early modern period, and Amjad Jaimoukha (2005) proposes to reconstruct some of the elements of their pre-Islamic religion and mythology, including traces of ancestor worship and funerary cults. The Nakh peoples, like many other peoples of the North Caucasus such as Circassians and Ossetians, practised tree worship, and believed that trees were the abodes of spirits. Vainakh peoples developed many rituals to serve particular kinds of trees. The pear tree held a special place in the faith of Vainakhs. Comparative mythology K. Sikhuralidze proposed that the peoples of the Caucasus region shared a single, regional culture in ancient times. Careful study of the Nakh and Kartvelian mythologies reveals many similarities. Jaimoukha (2005) adduces comparison with the Circassians, but also more generally with the Iron Age mythology of western Indo-European cultures, especially emphasizing parallels to Celtic polytheism, such as the worship of certain trees (including, notably, a pine tree on the winter solstice, supposedly related to the modern Christmas tree, reconstructed calendar festivals such as Halloween and Beltane, veneration of fire, and certain ghost related superstitions). Pantheon Jaimoukha (2005) on page 252 gives a list of reconstructed "Vainakh deities". Dal (Chechen), Däl (Ingush), or Dala - The supreme god. Equivalent to Greek Zeus, Roman Jupiter, Germanic Wodan and Circassian Theshxwe. Gal-Yerdi or Gela - Sun-god and patron of cattle breeders. Worshipped on the Nakh New Year's Day, and offered metal orbs and candles, as well as animal sacrifices at times. Hela - God of darkness. Seela or Sela - God of stars, thunder and lightning. Sela is often portrayed in Vainakh myth as an evil and cruel god. His skein (a loose bag made of animal skin) held the "night" (stars, lightning and thunder). He lives on the top of Mount Kazbek with his fiery chariot. It was he who chained Pkharmat to a mountain for stealing fire, and for this reason, on the Wednesday of his month in the old Vainakh calendar, it was forbidden to carry embers or ashes. During the era of Christianization in Chechnya and Ingushetia, he was (like the Ossetian Watsilla and the Russian Ilya-Muromyets) identified with the prophet Elijah, thus keeping his status. He is also, like the Greek Zeus, unable to control his desires for human women (much to the dismay of his wife, Furki), and one episode
