The Online Corpus of the Inscriptions of Ancient North Arabia [OCIANA] aims to help transform our knowledge of the history, languages and cultures of ancient Arabia by creating a digital corpus of all known Ancient North Arabian inscriptions in North and Central Arabia, and elsewhere. For each inscription, it provides a reading the text in roman transliteration, together with a translation in English, references to earlier readings, commentary where necessary, bibliography, and all known information about the inscription (provenance, relationship to other texts or to rock drawings and/or symbols, structures, etc.). Photographs (when available) and/or facsimiles of each text also appear on each record and are downloadable free at publishable resolutions whenever the original is good enough. The Corpus is constantly updated as new discoveries are made and is fully searchable for names, words, grammatical features and subjects, as well as genealogies, narratives and prayers.
