that supplies of grain were laid up for the maintenance of the hidden 103 fugitives, and De Rossi describes certain crypts in the Catacomb of Callixtus which were probably employed for storing corn or wine in time of persecution. Frequent wells occur, amply sufficient for the supply of water; and the multitude of lamps which have been found would dispel the darkness, while their sudden extinction would prove the best concealment from attack by their enemies.[149] Hence the Christians were stigmatized as a skulking, darkness-loving race,[150] who fled the light of day to burrow like moles in the earth. These worse than Dædalian labyrinths were admirably adapted for eluding pursuit. Familiar with their intricacies, and following a well-known clew, the Christian could plunge fearlessly into the darkness, where his pursuer would soon be inextricably lost. Perchance the sound of Christian worship, and the softened cadence of the confessors’ hymn, stealing through the distant corridors, may have fallen with strange awe on the souls of the rude soldiery stealthily approaching their prey; and, perhaps, not unfrequently with a saving and sanctifying power. But sometimes, tracked by the sleuth-hounds of persecution, or betrayed by some wretched apostate consumed by a Judas-greed of gold, the Christians were surprised at their devotions, and their refuge became their sepulchre. Such was the tragic fate of Stephen, slain even while ministering at the altar; such the event described by Gregory of Tours, when a hecatomb of victims were immolated at once by heathen hate; such the peril which wrung from a stricken heart the cry, not of anger but of grief, _Tempora infausta, quibus inter sacra et vota ne in cavernis quidem salvari 104 possimus!_--“O sad times in which, among sacred rites and prayers, even in caverns, we are not safe!” It requires no great effort of imagination to conceive the dangers and escapes which must have been frequent episodes in the heroic lives of the early soldiers of the cross.
