Giotto di Bondone's Lantern

Origin
A 13th century medieval painter and architect, Giotto is considered as one of the first great artists of the Renaissance. Giotto’s style was a noticeable break from preexisting styles, favoring the use of natural positions in his figures. Giotto's masterwork is the decoration of the Scrovegni Chapel in Padua, also known as the Arena Chapel, completed around 1305. This fresco cycle depicts the Life of the Virgin and the Life of Christ. Almost every other aspect of it is subject to controversy: his birthdate, his birthplace, his appearance, his apprenticeship, the order in which he created his works, whether or not he painted the famous frescoes at Assisi, and his burial place.

Effects
Became imbued with the power to bring one's art to life. The figures that come from the art slowly become real and are unable to return to their original artwork, the effects are vice versa for people who enter the art.
