Really enjoyed this. Working against an essentialist framework, Dursteler argues that identity was socially constructed with reference to religious, national, ethnic, cultural (etc.) categories, which were mutable and more easily permeated than the "clash of civilizations" suggests possible. Interesting prosopography of the Venetian national community in Constantinople; have a feeling that this may be the kind of book I want to write. Have yet to think through possible criticisms.
