It covers the dedicatory inscription on a ceremonial object donated to a synagogue that reflects the emotions and aspirations of the donor that conveys information relating to the event or person commemorated or honoured. It also explains how inscriptions can contribute significantly to the study of the community's customs, social life, and history. The chapter explores the tradition of having a dedicatory inscription that is known from ancient times, from inscriptions in the mosaic floors of synagogues. It also analyses the inscription of a name as a means of establishing the donor's rights that is mentioned in medieval halakhic sources.
