Under conditions where Balkan literatures have been treated as an alternative history of the Balkan, the author intends to see the role and power of literary work in creation, in changing or rejecting the image for/of the Other/stranger. The analysis covers several areas： the dominant position of image constructions; acts of invention an in（ter）vention; forming and transforming the images of the stranger; the role of stereotypes and prejudice in constructing images; the role of the discursive communities in creating images; and the role of the projective ideology in creating images.展开更多
