English: figures used in "oyunlar" (plays) around Karagöz. Wikipedia has an interesting entry, from which I quote: “Karagöz (meaning blackeye in Turkish) and Hacivat ( shortened in time from "Hacı İvaz" meaning "İvaz the Pilgrim", and also sometimes written as Hacivad) are the lead characters of the traditional Turkish shadow play, popularized during the Ottoman period. The central theme of the plays are the contrasting interaction between the two main characters. They are perfect foils of each other: Karagöz represents the illiterate but straightforward public, whereas Hacivat belongs to the educated class, speaking Ottoman Turkish and using a poetical and literary language. Although Karagöz has definitely been intended to be the more popular character with the Turkish peasantry, Hacivat is always the one with a level head. Though Karagöz always outdoes Hacivat’s superior education with his “native wit,” he is also very impulsive and his never-ending deluge of get-rich-quick schemes always results in failure. Hacivat continually attempts to “domesticate” Karagöz, but never makes progress.”
