with mosaics showing the councils of the church. Manuel was one of the patrons of the work. On the south wall, an inscription in Greek reads: "the present work was finished by Ephraim the monk, painter and mosaicist, in the reign of the great emperor Manuel Porphyrogennetos Komnenos and in the time of the great king of Jerusalem, Amalric." That Manuel's name was placed first was a symbolic, public recognition of Manuel's overlordship as leader of the Christian world. Manuel's role as protector of the Orthodox Christians and Christian holy places in general is also evident in his successful attempts to secure rights over the Holy Land. Manuel participated in the building and decorating of many of the basilicas and Greek monasteries in the Holy Land, including the church of the Holy Sepulchre in Jerusalem, where thanks to his efforts the Byzantine clergy were allowed to perform the Greek liturgy each day. All this reinforced his position as overlord of the Crusader states, with his hegemony over Antioch and Jerusalem secured by agreement with Raynald, Prince of Antioch, and Amalric, King of Jerusalem respectively. Manuel was also the last Byzantine emperor who, thanks to his military and diplomatic success in the Balkans, could call himself "ruler of Dalmatia, Bosnia, Croatia, Serbia, Bulgaria and Hungary". Manuel died on 24 September 1180, having just celebrated the betrothal of his son Alexios II to the daughter of the king of France. He was laid to rest alongside his father in the Pantokrator Monastery in Constantinople. Thanks to the diplomacy and campaigning of Alexios, John and Manuel, the empire was a great power, economically prosperous, and secure on its frontiers; but there were serious problems as well. Internally, the Byzantine court required a strong leader to hold it together, and after Manuel's death stability was seriously endangered from within. Some of the foreign enemies of the Empire were lurking on the flanks, waiting for a chance to attack, in particular the Turks in Anatolia, whom Manuel had ultimately failed to defeat, and the Normans in Sicily, who had already tried but failed to invade the Empire on several occasions. Even the Venetians, the single most important western ally of Byzantium, were on bad terms with the empire at Manuel's death in 1180. Given this situation, it would have taken a strong emperor to secure the Empire against the foreign threats it now faced, and
