Cedrenus makes mention of a lamp, which, together with an image of Christ, was found at Edessa, in the reign of the Emperor Justinian. It was set over a certain gate there, and privily enclosed, as appeared by the date of it, soon after Christ was crucified: it was found burning, as it had done for five hundred years before, by the soldiers of Cosroes, king of Persia, by whom also the oil was taken out, and cast into the fire; which occasioned such a plague, as brought death upon almost all his forces. - At the demolition of our monasteries here in England, there was found, in the supposed monument of Constantius Chlorus, (father to the Great Constantine,) a lamp, which was thought to have. continued burning there ever since his burial, which was about three hundred years after Christ. The ancient Romans used in that manner to preserve lights in their sepulchres a long time, by the oil of gold, resolved by art into a liquid substance.
