On the basis of stylistic analysis of works located in the church in Kasinka Mała, the relief in question may be attributed to Stanisław Ciężadlik, an author of sacral art works, who cooperated with the parish in Kasinka for many years. Stanisław Ciężadlik (1912-1996) was a painter, sculptor, musician, scenographer, creator of puppets and a puppeteer. This talented artist made a range of works in the church in Kasinka Mała: two altars, baptismal front, confessional and two portraits of parish priests.
