Croatian folklorist Maja Bošković-Stulli noted that the theme was explored as the subject matter of a Serbo-Croatian epic song: Pero Vitkovic offers to bring the Banica of Misir (the margravine of Egypt) as bride to Viennese Prince Karlo, despite his mother's objections. On the way there, Pero overhears a carrier pigeon describing the three perils Karlo and the margravine will have to face until their wedding, and notices that the carrier pigeon belongs to Karlo's mother, the Empress.
