This is a pedagogical edition of a section of Ramon Muntaner’s Catalan Crònica (ca. 1230) relating the events leading up to the so-called ‘Catalan vengeance,’ in which the Catalan company who had been invited by the Byzantine Emperor to defend Constantinople were deceived, massacred, and then launched a bloody counterattack that earned them control of a large territory in the Eastern Mediterranean. Edition of Catalan text, introduction, and translations into English and Spanish by Vicente Lledó-Guillém (2019).
