The present paper deals with attacks against houses motivated by interpersonal differences in the Imperial Period. The well-known episode of the attack against Tryphera’s house in Knidos is put against the background of relevant information drawn from Egyptian papyri and the work of Roman jurists. The main argument is that the principle of self-help could potentially be invoked by both parties in such conflicts and that this particular form of violence could not only be disapproved but also tolerated by the community and the various levels of state authority, according to the circumstances.
