A renewed interest sprang up when pilgrims began to return from their journeys to Palestine, bringing with them, as was natural, some souvenirs of their sojourn. A most interesting quotation from Mackay reveals the condition of these times. "The first pilgrims to the Holy Land brought back to Europe thousands of apocryphal relics, in the purchase of which they had expended all their store. The greatest favorite was the wood of the true cross, which, like the oil of the widow, never diminished. It is generally asserted, in the traditions of the Romish Church, that the Empress Helen, the mother of Constantine the Great, first discovered the veritable '_true cross_' in her pilgrimage to Jerusalem. The Emperor Theodosius made a present of the greater part of it to St. Ambrose, Bishop of Milan, by whom it was studded with precious stones and deposited in the principal church of that city. It was carried away by the Huns, by whom it was burnt, after they had extracted the valuable jewels it contained. Fragments, purporting to have been cut from it, were, in the eleventh and twelfth centuries, to be found in almost every church in Europe, and would, if collected together in one place, have been almost sufficient to have built a cathedral. Happy was the sinner who could get a sight of one of them; happier he who possessed one! To obtain them the greatest dangers were cheerfully braved. They were thought to preserve from all evils and to cure the most inveterate diseases. Annual pilgrimages were made to the shrines that contained them and considerable revenues collected from the devotees.
