Dielli (Albanian indefinite form Diell), the Sun, holds the primary role in Albanian pagan customs, beliefs, rituals, myths, and legends. Albanian major traditional festivities and calendar rites are based on the Sun, worshiped as the god of light, sky and weather, giver of life, health and energy, and all-seeing eye. In Albanian tradition the fire – zjarri, evidently also called with the theonym Enji – worship and rituals are particularly related to the cult of the Sun. Ritual calendar fires or bonfires are traditionally kindled before sunrise in order to give strength to the Sun and to ward off evil. Many rituals are practiced before and during sunrise, honoring this moment of the day as it is believed to give energy and health to the body. As the wide set of cultic traditions dedicated to him indicates, the Albanian Sun-god appears to be an expression of the Proto-Indo-European Sky-god (Zot or Zojz in Albanian).
Albanians were firstly described in written sources as worshippers of the Sun and the Moon by German humanist Sebastian Franck in 1534, but the Sun and the Moon have been preserved as sacred elements of Albanian tradition since antiquity. Illyrian material culture shows that the Sun was the chief cult object of the Illyrian religion. Finding correspondences with Albanian folk beliefs and practices, the Illyrian Sun-deity is figuratively represented on Iron Age plaques from Lake Shkodra as the god of the sky and lightning, also associated with the fire altar where he throws lightning bolts. The symbolization of the cult of the Sun, which is often combined with the crescent Moon, is commonly found in a variety of contexts of Albanian folk art, including traditional tattooing, grave art, jewellery, embroidery, and house carvings. Solemn oaths (be), good omens, and curse formulas, involve and are addressed to, or taken by, the Sun. Prayers to the Sun, ritual bonfires, and animal sacrifices have been common practices performed by Albanians during the ritual pilgrimages on mountain tops.
