František Tkadlík is one of the most prominent painters of the first half of the 19th century. His artwork bordering classicism and romanticism includes a wide scope of styles: portraits as well as mythological, historical, and mainly religious themes. The painting St Wenceslas and St Ludmila during the Mass was painted shortly after Tkadlík assumed the position of headmaster of the Academy of Fine Arts in Prague. In this canvas, he depicted the intimate atmosphere of a spiritual moment, non-affectedly combining its religious and historical character. The painting hence became an example of patriotic art which affected the new generation of artists including Josef Mánes.
