[164] "Ildebrando del Giudice, Uberto Leone, Signoretto Alliata e Buschetto da Dulichio che fu Architetto; il capo di detti fu Ildebrando e gli altri furono Ministri e Uffiziali dell' Opera, come si trova nell' Archivio di detta Opera."

[166] Among these were the two porphyry columns now at the door of the Baptistery in Florence. They were taken by the Pisans 1107 from the Saracens in Majorca, and as they were especially valuable, being miraculous, the Florentines claimed them as the spoils of war in 1117. They were said to guard people against treachery.
[167] There was a Diotisalvi, a Judge at Pisa in the year 1224, and a Diotisalvi, son of Bentivenga, is mentioned in a deed executed in 1250, in the Port of Pisa. These may have been some of the architect's distant descendants, but we have no clue as to his ancestors. The name would seem to have been a nickname, and not his baptismal one, for in another round church which he built in Pisa, the Knights Templars' church of S. Sepolcro, it is engraved, "Hugius operis Fabricator D͞STESALVET nominatur." The author of Lettere Senesi derives the name from the motto of the Petroni family in Siena.
