Inside the St. John Cantius church in Kęty, there is a votive painting depicting one of the temple's most notable donors, reverend Grzegorz Jan Zdiewoyski from Łask. The painting funded by him in 1653, displays a clergyman entrusting himself to the protection of John Cantius, whom he worshipped with particular zealously.
