Perkunas was the Lithuanian Lord of Fire who became the chief deity of the Lithuanian pantheon of gods and goddesses. Despite this being a chief god, he was subordinate to the goddess Lamia.
According to my research Lithuania was one of the last countries to convert to Christianity. During the 16th century the Jesuits were dismayed by the worship of Perkunas and sacred trees-the oaks. Perkunas was also known for reviving Earth’s fertility. The first clap of thunder sleeping earth awake and purifies the water. The people of the region would wait for the thunder to await Perkunas’ blessing. The first clap of thunder was also the time when the spring gardening would begin as well. Since Perkunas was keeper of the rain then he governed fertility and abundance. Perkunas is a guardian of justice but can also be restless and ruthless.
Perkunas was a defender of the good and banishes evil. Tress that were struck by lightning were seen as a blessing. He was called upon to cure toothaches and fevers. Lighting was often connected to fertility for this reason. When thunder and lightning fell from the sky on Saint George’s Day (April 23) was an especially good time for Perkunass’ blessing. If there is no thunder during springtime this was a bad time. Perkunas hates liars, thieves, and selfish sons. He honors soldiers, warriors, farmers, and anyone lucky enough t survive being struck with lightning. Described as a handsome guy with a copper beard or when angry he becomes a middle-aged man with a twisted black beard. His sacred day is Thursday or Thor’s Day. Not is St. George’s Day he is also revered on Easter, as well as June 24, June 29, and October 1st. His scared tress are oak and ash.
