As to the addition of the further documents, it may be observed that after the papers were put together the collection ended with six second pages, of which four, 448, 449, 450, 451, belonged to the opinion of Pasqualigus; and two, 452, 453, to the protocol of the examination of Galileo of 12th April, 1633. The annotation about the decree of 16th June, 1633, was written on the reverse side of the last second page, 451, forming part of the above-named document, and the three previous pages were left blank. The protocol on the Constitute of Galileo of 21st June was written on the blank sheets of 12th April. On the remaining space (half of 453 and the reverse side) two notes were made—the first about the mandate of 30th June, to send the sentence and recantation to all Inquisitors, etc., and the permit to Galileo to go to Siena; the second note reports that Firenzuola issued the order to Galileo on 2nd July. The rest of the documents which the Vatican MS. now contains must have been added as they came in, or when there were several to be added. The paging was, of course, continuously carried out. The last document but one of the collection is a short historical summary of the process. Berti says that this must have been drawn up at least a year after its conclusion,[637] but Pieralisi[638] has pointed out that he should have said, at least a century. The origin of it is plain: when the inquiry of Fra Paolo Antonio Ambr*** of 8th June, 1734, came in as to the erection of a monument in Santa Croce, this _résumé_ was drawn up to put the cardinals, who might not know much about it, in possession of the chief facts of Galileo’s trial. In the Vatican MS. the sheet of paper containing the _résumé_ is stitched to the letter of Fra. Ambr*** and the decision of the cardinals written on the fourth page. If any doubts remain that this summary was written in 1734, they will disappear on comparing it with the extracts, published by Gherardi, of the protocol of the sitting of 16th June of that year. In this we find, within parentheses, the most important part of the summary, followed by the decision of the cardinals, in almost verbatim translation from Italian into Latin. The date and purpose of the summary are therefore made clear. III. _ESTIMATE OF THE VATICAN MANUSCRIPT._
