Hrnjica brothers are heroes of epic poetry in Bosnia. The names of the brothers are Mujo, Halil and Omer. The epic poetry also mentions their beautiful sister Ajkuna (Bosnian: Lijepa Ajkuna). Mujo is hypocorism of Mustafa.[1] There are several toponyms in the region of Velika Kladuša named after Hrnjica brothers, i.e. Well of Hrnjica (Bosnian: Hrnjičin bunar) or the Tower of Hrnjica (Bosnian: Hrnjičina kula).[2] Songs about the Hrnjica brothers can usually be put in the "Krajišnik" cycle (Bosnian: pjesme o Krajišnicima). (transl. songs about the Frontiersmen)This cycle deals with the frequent raids and battles that happened in Bosnia, which at one time was a border province of the Ottoman Empire.[3]
