1504. On the 9th day of August, 1504, I took 10 florins in gold[2] ... [3] on Friday the 9th day of August fifteen grossoni that is fl. 5 S 5 ... given to me 1 florin in gold on the 12th day of August [4] ... on the 14th of August, 32 grossoni to Tommaso. On the 18th of the same 5 grossoni to Salai. On the 8th of September 6 grossoni to the workman to spend; that is on the day of our Lady’s birth. On the 16th day of September I gave 4 grossoni to Tommaso: on a Sunday.
[Footnote: In the original, the passage given as No. 1463 is written between lines 2 and 3 of this text, and it is possible that the entries in lines 3 and 4 refer to the payments of Jacopo Tedesco, who is there mentioned. The first words of these lines are very illegible.]
[Footnote 7: Al fattore. Il Fattore, was, as is well known, the nick-name of Giovanni Franceso Penni, born in Florence in 1486, and subsequently a pupil of Raphael’s. According to Vasari he was known by it even as a boy. Whether he is spoken of in this passage, or whether the word Fattore should be translated literally, I will not undertake to decide. The latter seems to me more probably right.]
