According to Giazotto, he obtained the document shortly after the end of World War II from the Saxon State Library in Dresden which had preserved most of its collection, though its buildings were destroyed in the bombing raids of February and March 1945 by the British and American Air Forces. Giazotto concluded that the manuscript fragment was a portion of a church sonata ("sonata da chiesa", one of two standard forms of the trio sonata) in G minor composed by Albinoni, possibly as part of his Op. 4 set, around 1708.
