It is clear from this letter that the curia made at least one attempt to regain possession of the Vat. MS. between 1820 and 1845, and Gherardi concludes from the circumstance that this letter was found with the said collection that a copy of it had been sent to the Count, perhaps to show him that it was desired to put all the papers relating to Galileo’s cause together—a project intended to urge the Count to renewed efforts for their recovery. Be that as it may, the important thing is that Gherardi, having convinced himself of the entire agreement of his ten extracts (the most important), with the corresponding ones in the collection, concluded that the other twenty-two were correct, and did not make any more extracts. In April, 1849, in spite of the precautions taken, the Archives of the Inquisition seemed no longer safe from the mob, and were removed, with other ecclesiastical libraries, to the Apollinarius church, where Gherardi was again able to look at them. But it was but for a moment, as he decidedly declined all responsibility for a collection of such immense historical value. Moreover, the advance of the French army to Rome to effect the restoration of Pius IX., would have left him but little time for historical researches. On 4th July, in consequence of the capitulation of the municipal council, the French General Ouidinot marched at the head of his troops into “liberated” Rome, while Garibaldi left it on the other side with his 4000 volunteers, and with him all the patriots who had specially distinguished themselves in the service of the Republic during its short existence. Among these was Gherardi, who turned his steps towards Genoa, where he lived for his studies during his exile. On leaving Rome he had only been able to take ten extracts with him, and had now to wait for an opportunity of completing them by those in the Archives of the Inquisition, and he waited patiently twenty-one years. In 1870 the time at length came. He gives us no further particulars as to how he succeeded in getting the collection into his hands again, but simply says that he did so, and no longer delayed to give this valuable historical material to the world. The history of Gherardi’s Documents is of itself a pledge of their authenticity, and it is absolutely confirmed by comparing them with the corresponding documents of the Vatican MS. We have compared them line for line and word for word, and have found that they contain nothing Whatever that in the least diverges from those Acts. On the contrary, they throw light on and complete them, and in some cases agree with them verbatim—perhaps the best possible proof of the authenticity of both. V. DECRETVM[644] 989. Fol. 380 ro. 38
