In the spring of 630, Heraclius made the pilgrimage to Jerusalem, walking barefoot to Constantine’s Church of the Holy Sepulchre to return the True Cross to the Holy City. He was riding high on a wave of popularity, but he soon discovered that his triumph over the Persians brought with it the familiar specter of religious dissension. Syria and Egypt had always been Monophysite, and their re-absorption into the empire ensured that the religious debate was reopened with a vengeance. Such a state of affairs was an ominous weakness for the next invader to exploit, but where faith was involved, not even the conqueror of Persia could force his stubbornly independent inhabitants to fall into line.

The wife of Justinian’s successor mocked the ninety-year-old eunuch by sending him a golden distaff with a letter of dismissal. “Since you are not a man,” it supposedly read, “go spin wool with the women.” Enraged by the unnecessary insult after a lifetime of service, Narses muttered that “he would tie her such a knot that she would not unravel it in her lifetime.” Preparing to go into retirement in Naples, he spitefully invited the12
