Voloska, sometimes dubbed Vlasta, is a Croatian and Slavic hearth pseudo-deity that has not been attested in historical sources on Slavic paganism. The first known published source that attests to Voloska is the 1943 book Hrvatska narodna mitologija ("Croatian National Mythology") by psychiatrist Nikola SuÃÂiÃÂ, which has been criticized by Croatian ethnologists as "incorrectly assessing" pagan myths and as unreliable due to a lack of sources.
According to SuÃÂiÃÂ, Voloska was the spouse of Veles and the protector of agricultural workers, symbolized by a cow and a swallow. He claims that all Slavic homes featured an alcove ("mirià ¡te") where a small flame would be lit in Voloska's honor. This alcove would allegedly also include statuettes of Voloska made from wood, wax or amber.
After the publishing of SuÃÂiÃÂ's book, Voloska was mentioned in the poems of Vladimir Nazor ("Miti i legende", 1948) and Boro PavloviÃÂ ("Slavenska lipa", 1960).
Commonly cited publicist and movie director Franjo LediÃÂ, whose interpretation of Slavic mythology was described as "romanticized" by ethnologist Tea à  kokiàand "uncritical" by Lidija Bajuk, wrote a chapter on Voloska based on the work of SuÃÂiàand the previously mentioned poems.
