Latvian mythology
Latvian mythology is based primarily off collections of folklore and song texts. Much of the information presented herein, and in the best sources on the subject, is purely speculation based off very limited facts.
In AD 98, Tacitus, a Roman, mentioned the worship of mahtes, goddesses in the old Latvian mythology. Tacitus, however, did not speak Latvian and spent little time there. Later, reports of Christianization give similarly unbalanced information. We do know that some tribes had had their religious beliefs declining for some time, and accepted Christianity willingly. Others, such as the Curonians[?] and Semigallians[?], resisted Christianization. Later texts by authors who presumably knew nothing of Latvian beliefs, substituted supposedly authoritative work substituting Prussian deities, adding extremely unlikely explanations and etymologies.
The deities were believed to live on a mountain called Debeskalns.
The Latvians recognized eight different seasons to the year. The end of one season and the beginning of the next was marked by a festival.
