Complex relations of a lie and a human world are a big topic in literature and myths. Firstly this topic is open in a broader and more general sense with a ques-tion on a lie being a defect or a competence. Next the author applies philological and historic approach in reading ancient Indo European and particularly Slavon-ic mythological traditions and he observes an unusual type of the lie closely re-lated to wisdom and authority. He tries to add heavenly wily lawyers, which lie or commit perjury with beneficial cosmogonic or sociogenic effect, to the Dumézil´s catalogue of unusual characters of Indo European mythology. Some characters from selected Slavonic mythopoetic traditions are pointed out.
