Abstract
The paper aims to show that by abstracting from a specific mythical historical-
stylistic context and “ideation” of the notion of the Proto-Slavic deities Perun
and Veles, especially in Croatian tradition, symbolic archetypes and abstract notions
of form and primordial matter (materia prima) can be extracted from mythical
content. We refer to mythical texts and contents according to the reconstructions
and materials brought by Radoslav Katičić, and comparative analysis by Mislav
Ježić. We distinguish form (1) as that in which identity and possibility of a thing
consists, (2) as the reasonableness of judgment and the form of existence, and (3) as
the specific structure of a thing, which unites its parts and aspects as a whole and
constitutes its internal necessity. These formative notions are relativized and nullified
in Veles’ appearances, in which the archetypal notion of primordial matter
is encoded. Examples of Platō’s dialogues historically confirm certain aspects of
decoding myth as constitutive of philosophy. The above approach also opens a
view of the roots of Croatian philosophical thought, which in its genesis can be
traced back to Proto-Slavic mythical archetypes. With the implementation of Christianity,
the questions of identity, reason and the structure of the whole are raised
radically and sharply, as shown by the text of Trpimir’s grant (852).
