He further gives us more in detail[48] an idea of the continual accumulation of riches which were derived from the exposure of these relics to the sick and infirm and the consequent growth in wealth of the monasteries and cathedrals. The monastic system was probably most responsible for the change from the simple adoration of the early Christians to the use of relics as a miraculous means of healing. Those which were transported with elaborate ceremonies, enclosed in a magnificent stone sarcophagus, and covered by an edifice of imposing proportions were almost sure to bring to their custodians great wealth. It is said that when the body of St. Sebastian, which was legitimately obtained from Rome, together with the purloined remains of St. Gregory, reached the cloister of Soissons, so great was the crowd of invalids who were cured, and so generous were they in their donations, that the monks actually counted eighty measures of money and one hundred pounds in coin. The great value of such objects may be calculated when it is remembered that in the year 1056 securities amounting to ten thousand solidi were pledged for the production of the relics of St. Just and St. Pastor, consequent upon the legal decision of ownership between Berenger, a French ruler, and a Narbonnese archbishop. The Reichberg annals provide a further example. They state that the emperor demanded certain hostages, or the holy arm of St. George, as a suitable guarantee for the institution of a public mart in Germany. Venetian merchants were among the first to realize the commercial value of relics, and enjoyed a lucrative traffic in this holy merchandise. It was not until the eleventh century, however, that the government of Venice founded public marts or fairs for the commercial exchange of saintly relics, although Rome and Pavia had long conducted such enterprises. These fairs were placed under the tutelary protection of some patron saint, the Venetians, of course, thus honoring St. Mark. They were not always particular how these relics were procured, for it is stated that when negotiations for the exchange of a well-preserved body of St. Tairise proved unsuccessful, because the Greek monks who possessed it refused absolutely to sell or barter, these enterprising traders quietly stole the desired skeleton. Relics provided a suitable method of acquiring ecclesiastical fortunes for denuded cloisters or impoverished nunneries; and if the old relics lost their power it was not difficult to procure episcopal assurance of the miraculous powers of new ones. For the procuring of special funds the venerated objects were taken from place to place, under priestly surveillance, presented to the sick and infirm with assurance of relief, and with the demand for large sums of money.
