nearby provinces of Syria, Phoenicia, and Arabia. Nevertheless, there was a continuous small Jewish presence and Galilee became its religious center. Some of the Judean survivors resettled in Galilee, with some rabbinical families gathering in Sepphoris. The Mishnah and part of the Talmud, central Jewish texts, were composed during the 2nd to 4th centuries CE in Galilee. Jewish communities were still present on the edges of Judea, including Eleutheropolis, Ein Gedi and the southern Hebron Hills. There were also Jewish communities along the coastal plain, in Caesarea, Beit She'an and on the Golan Heights. In the aftermath of the defeat, the maintenance of Jewish settlement in Palestine became a major concern of the rabbinate. The Sages endeavoured to halt Jewish dispersal, and even banned emigration from Palestine, branding those who settled outside its borders as idolaters. Roman losses Cassius Dio wrote that "Many Romans, moreover, perished in this war. Therefore, Hadrian, in writing to the Senate, did not employ the opening phrase commonly affected by the emperors: 'If you and your children are in health, it is well; I and the army are in health.'" Some argue that the exceptional number of preserved Roman veteran diplomas from the late 150s and 160 CE indicate an unprecedented conscription across the Roman Empire to replenish heavy losses within military legions and auxiliary units between 133 and 135, corresponding to the revolt. As noted above, XXII Deiotariana may have been disbanded after serious losses. In addition, some historians argue that Legio IX Hispana's disbandment in the mid-2nd century could have been a result of this war. Previously it had generally been accepted that the Ninth disappeared around 108 CE, possibly suffering its demise in Britain, according to Mommsen; but archaeological findings in 2015 from Nijmegen, dated to 121 CE, contained the known inscriptions of two senior officers who were deputy commanders of the Ninth in 120 CE, and lived on for several decades to lead distinguished public careers. It was concluded that the Legion was disbanded between 120 and 197 CE—either as a result of fighting the Bar Kokhba revolt, or in Cappadocia (161), or at the Danube (162). Legio X Fretensis sustained heavy casualties during the revolt. Other casualties The revolt was led by the Judean Pharisees, with other Jewish and non-Jewish factions also playing a role. Jewish communities of Galilee who sent militants to the revolt in Judea were largely spared
