On 30 December 1066 (9 Tevet 4827), Muslim mobs stormed the royal palace where Joseph had sought refuge, captured and crucified him. In the ensuing massacre of the Jewish population, many Jews of Granada were murdered. The 1906 "Jewish Encyclopedia" claims, "More than 1,500 Jewish families, numbering 4,000 persons, fell in one day." However, the 1971 edition does not give precise casualty figures. That was possibly because the accounts of the massacre could not be verified, and as over 900 years had passed, it was subject to hyperbole. The "Encyclopaedia Judaica" also confirms the figures : "According to a later testimony, "more than 1,500 householders" were killed".
