Padua Aramaic papyri
The Padua Aramaic papyri are a group of three Aramaic papyri thought to be from the 400s BCE, found in a collection of antiquities in the Italian city of Padua. The papyri are unprovenanced, but are thought to have been from Elephantine, which would make them the first Elephantine papyri and ostraca to have been discovered (although published much later than most). They were acquired by Giovanni Belzoni in c.1815, together with a demotic letter; Belzoni presented them to the Musei Civici di Padova in 1819. They were first published in 1936 by Luigi Gaudenzio in a  group of unrelated documents; they first received scholarly attention after their 1960 publication by Edda Bresciani. They are currently in the Musei Civici di Padova, and are also known as TSSI II 28. They are considered to form part of the corpus of Elephantine papyri and ostraca; Bresciani wrote as follows: The letter referred to in this publication as "Papyrus I" shows that the recipient was in Elephantine, as he begins with greetings at the temple of Yaho in Elephantine. This, if it is not absolutely decisive for affirming that Elephantine is also the place of discovery, nevertheless makes it  probable. The "Papyrus III" still suggests Elephantine, since it reads ... and ... is the term commonly used in the Aramaic Elephantine papyri to indicate the temple of Yaho on the island. In "Papyrus II" is mentioned a ..., which therefore bears an Egyptian proper name, frequent and typical of Elephantine where Khnum was the local god. On this basis, I would propose, naturally without absolute certainty, Elephantine, as the possible common place of origin of the papyri.
