The painting depicting the Holy Trinity was created for the altar of St. Sebastian in the 1750s. It was painted in the workshop of the Kornecki family, probably by Piotr Kornecki himself, who was a painter and a sculptor by trade. The Holy Trinity was depicted in the New Testament type, most popular in its modern images, in which all representational elements can be found in the Holy Scripture.
