Holy Fire
Under Baldwin I, Latin clergy had taken over the Holy Sepulchre, and according to Christopher Tyerman, the Greek clergy were restored "after the fiasco of the failure of the regular Easter miracle of the Holy Fire under Latin auspices in 1101, the annual ritual on Easter eve when Holy Fire is supposed to descend from heaven to light the priests' candles in the edicule of the Holy Sepulchre. The newcomers evidently had not learnt the knack."
