Excited by a discovery the capital importance of which he was able to foresee at once, he asked an audience of the Pope, Pius IX., and begged him to purchase the Vigna Molinari, and grant the funds necessary to discover the crypt to which this fragment of a tombstone belonged. After listening quietly to the arguments by which the young man was advocating his cause, the Pope answered only four disheartening words: "Sogni di un archeologo!" (dreams of an archæologist). At the same time he gave orders for the immediate purchase of the vigna (now called dei Palazzi Apostolici) and for the appropriation of an "exploration fund." In March, 1852, a crypt was discovered on the very border of the Appian Way; in the crypt was a tomb, and with it were the missing fragments of the epitaph of Cornelius. Some weeks later the young discoverer escorted the Pope to the historical grave, and pointing to the epitaph exclaimed: "Sogni di un archeologo!" To judge of the importance of the discovery we must remember that the identification of the crypts of Lucina, and that of all the surrounding catacombs, depended mostly upon the identification of this one. The "Liber Pontificalis" says: "The emperor Decius gave judgment in the case of Cornelius: that he should be taken to the temple of Mars _extra muros_, and asked to perform an act of adoration: in case of a refusal that he should be beheaded. This was accordingly done, and Cornelius gave his life for his faith. Lucina, a noble matron, assisted by members of the clergy, collected his remains and buried them in a crypt on her own estate near the Cemetery of Callixtus, on the Appian Way; and this happened on September 14 (A. D. 253)." As the Cemetery of Callixtus was the recognized burial-place of the bishops of Rome, why was this exception made to the rule? The reason is evident: the estate of Lucina contained the family vault of the Cornelii, or at least of a branch of the Cornelian race. The victim of the persecution of Decius was the first Pope of noble and ancient lineage. Apparently his relatives wished to emphasize this fact in the place selected for his burial, and by proclaiming his illustrious descent on his gravestone through the use of the old and simple language of the republic,--"Cornelius Martyr." The use of Latin at this age constitutes another conspicuous exception to the rule, because the Greek language was not only fashionable in the third century, but had been adopted almost officially by the Church. The majority of liturgical words, such as hymn, psalm, liturgy, homily, catechism, baptism, eucharist, deacon, presbyter, pope, cemetery, diocese, are of Greek origin, and the names of the Popes in the pontifical crypt of this same cemetery are, likewise, written in Greek letters even when they are strictly Roman, as in the case of ΛΟΥΚΙΣ for LVCIVS.
