Architecture was not the only area of arts that boomed at that time. The patronage of wealthy and influential individuals, from kings through the nobility, as well as clergymen and town patricians, allowed various artists to create masterpieces. For example, Grzegorz of Sanok, Archbishop of Lwów, a poet himself, supported numerous scholars and writers, such as Filip Callimachus from Tuscany, who became a tutor to King Casimir's sons, and a professor at the Jagiellonian University. Buildings were adorned with gold and silver articles, paintings, stained glass windows, stone and wood sculptures, and textiles. Notable monuments include the sarcophagus of Casimir the Great in the Wawel Cathedral, the altar of St. Catherine's Church in Kraków by Mikolaj Haberschrack, the stained glass windows of Saint Nicholas's Church, Toruń, the reliquary for the head of Saint Stanisław, and the chasuble from the benefaction of Piotr Kmita. Byzantine art was also influential, represented in the frescoes of the Trinity Chapel in Lublin, and of Italian art in the Franciscan monastery in Kraków. One of the greatest examples of Gothic art in Poland are the works of Veit Stoss (Wit Stwosz), who came from Nuremberg to Kraków in 1477, staying there till his death twenty years later. His wooden altar, with hundreds of small figurines, has been described as "one of the crowning achievements of medieval sculpture."
