This second edition of A Corpus of Ammonite Inscriptions presents all of the published inscriptions that have been identified as Ammonite in one volume. Each entry is accompanied by a complete bibliography, a physical description and details about its location, a photograph and/or drawing, relevant linguistic information, and a history of the inscription’s interpretation. The discovery of the Amman Theater Inscription, Amman Citadel Inscription, Tall Sīrān Bottle, Ḥisbān Ostraca, and Tall al-Mazar Ostraca opened a new chapter in the study of ancient Northwest Semitic inscriptions with the recognition and analysis of the language and script of ancient Ammon. These new discoveries prompted a reclassification of a number of epigraphs previously identified as Hebrew, Phoenician, or Aramaic. Since the first edition of this corpus, the discussion of the criteria used to classify inscriptions as Ammonite, including provenance, language, onomastics, paleography, and iconography, has advanced considerably. In addition, the number of known inscriptions has increased. This updated edition includes 254 additional inscriptions, four new appendixes, and in many cases, new and improved images.
