There exists a fragment of the old Aleppo prayer book for the High Holy Days, published in Venice in 1527, and a second edition, starting with the High Holy Days but covering the whole year, in 1560. This represents the liturgy of the Musta'arabim (native Arabic-speaking Jews) as distinct from that of the Sephardim proper (immigrants from Spain and Portugal): it recognizably belongs to the "Sephardic" family of rites in the widest sense, but is different from any liturgy used today. For more detail, see Old Aleppo ritual.
