<p style='text-align: justify;'>Treatise on the calendar by Josiah b. Mevoraḵ al-ʿĀqūlī, which claims that the Jewish calendar repeats itself exactly every 247 years. He describes the course of the fourteen possible types of the Jewish year, including the beginning of months, holidays and fasts. One folio has marginalia in a different hand in Judaeo-Arabic and Arabic (apparently notes added by a reader), including a transliteration of calendrical information into Arabic characters.</p>
