He was a Bolognese, who travelled through Italy, and collected materials for a history of painting--consulted archives, sepulchral monuments, oral traditions, national annals, and the age of the artists. His 53 volumes were placed in the library of Prince Filippo Ercolani, who purchased them from his successors, and very kindly gave me the use of them for this work. The Cav. Gio. de Lazara, of Padua, assisted by Sig. Pietro Brandolese, of Lendinara, drew several inedited notices from these volumes, in addition to the number before extracted. They are added to this edition under two different heads, namely, _Oretti Carteggio_ and _Oretti Memorie_, or the initials of these words. Under the first are comprehended notices of different artists, communicated in letters to Sig. Oretti, or to others, which he procured. Under the second are the notices collected by himself from the places he passed through, in particular at Bologna, from authentic documents and registers, monuments, &c. He is frequently noticed throughout Index I. Orlandi, P. Pellegrino. _Dictionary of Painting._ Bologna, 1719, 4to. The author's letter preceding the work is dated 1718, to which period we refer the artists he therein mentions as living. Opinion of this work, _pref._ xiv. xx. Cited throughout the work.
