In April, Edward Reichman, an expert on the history of Jews and medicine, was asked to assess the historical significance of a medical diploma issued to a Jew named Rabbi Leon son of Samuel Cantarini by the University of Padua in 1623—discovered in the vast collection of a recently deceased German biologist. Reichman explains what is known about the remarkable Cantarini family, and about Leon himself, who went on to serve as a rabbinic judge in Padua and to establish a small yeshiva in that city.

Leon’s diploma is the earliest known extant diploma of a Jewish medical graduate of the University of Padua, and I believe it is the only extant diploma (of any kind) granted to a rabbi who is identified as such in the text. Furthermore, it possesses nearly all the alterations, accommodations, and features that can be found in the diplomas of the Jewish medical graduates of the University of Padua.

Considering the current state of Israel-Arab relations, Ghaith al-Omari writes

First and foremost, no ceasefire will be possible without the release of Israeli hostages and commitments to disarm Hamas and remove it from power. The final say on these matters rests with Hamas commanders on the ground in Gaza, who have been largely impervious to foreign pressure so far. At minimum, however, the United States should insist that Qatari and Egyptian mediators push Hamas’s external leadership to accept these conditions publicly, which could increase pressure on the group’s Gaza leadership.

Washington should also demand a clear, public position from key Arab states regarding disarmament. The Palestinian Authority President Mahmoud Abbas endorsed this position in a June letter to Saudi Arabia and France, giving Arab states Palestinian cover for endorsing it themselves.

Some Arab states have already indicated a willingness to play a significant role, but they will have little incentive to commit resources and personnel to Gaza unless Israel (1) provides guarantees that it will not occupy the Strip indefinitely, and (2) removes its veto on a PA role in Gaza’s future, even if only symbolic at first. Arab officials are also seeking assurances that any role they play in Gaza will be in the context of a wider effort to reach a two-state solution.

On the other hand, Washington must remain mindful that current conditions between Israel and the Palestinians are not remotely conducive to . . . implementing a two-state solution.
