Dzydzilelya is a Polish female deity, mentioned by 15th-century historian Jan Długosz in Annales seu cronici incliti regni Poloniae (History of Poland). He compares her with Venus. Most of contemporary scholars consider that Annales seu cronici incliti regni Poloniae isn't a trustworthy source on Slavic mythology. Aleksander Brückner claimed that the name of Dzydzilelya is derived from a meaningless song refrain, mistook by Długosz for a name of deity. However, some scholars suppose that Dzydzilelya was a West Slavic analogue of BulgarianDodola, presumably the goddess of rain and fertility.
