But other ecclesiastical bodies in that city were both pious and shrewd, and so we find that not far off, at the church of St.
Gereon, a cemetery has been dug up, and the bones distributed over the walls as the relics of St.Gereon and his Theban band of martyrs! Again, at the neighbouring church of St.Ursula, we have the later spoils of another cemetery, covering the interior walls of the church as the bones of St.Ursula and her eleven thousand virgin martyrs: the fact that many of them, as anatomists now declare, are the bones of MEN does not appear in the Middle Ages to have diminished their power of competing with the relics at the other shrines in healing efficiency.
No error in the choice of these healing means seems to have diminished their efficacy.

When Prof.Buckland, the eminent osteologist and geologist, discovered that the relics of St.Rosalia at Palermo, which had for ages cured diseases and warded off epidemics, were the bones of a goat, this fact caused not the slightest diminution in their miraculous power.
Other developments of fetich cure were no less discouraging to the evolution of medical science.

Very important among these was the Agnus Dei, or piece of wax from the Paschal candles, stamped with the figure of a lamb and consecrated by the Pope.
