Kabrca

The Kabrca is the only Slovene ocarina which was brought to life by Alenka Gololičič in collaboration with the Goriška regional museum, and the publicist and the owner of the Kabrca, Pavel Medvešček. His collected folk tradition shows that the Slavic native faith with the priests was present in the Soča Valley until the First World War. The ethnological collection of Pavel Medvešček comprises 257 objects originating from the central Soča Valley, that is from the right bank of Livške Ravne in the north through Kambreško and Volčanski Ruti to Livško in the south from the left bank and from Most na Soči through Tolminski Lom, Seniški Breg, Kalsko, the Banjšice Plateau to the Kanalski Vrh area. The objects are also from Čepovan, Cerkno, Idrija and the Brkini Hills. Most of the objects are from the central Soča Valley, actually from its right bank, from Kambreško and Volčanski Ruti. The Kabrca was one of the most important items. It is a meditative pipe used only by a Dehnar, the leader of the Slavic native faith followers in the Soča Valley, during his work, reflection and rituals. It was made from a mixture of local Soča clay and coloured with natural plant dyes.
