Italian school (XVIII) - Conclave

Antique oil painting on canvas 48x59; I think it is from the 1700s in good overall condition as shown in the photo, very well executed, surely by a good artist, coming from a very great and eminent medical surgeon Pasquale Mennonna who gave it to his nephew and I received it from the nephew, as stated by the nephew, as in the photo. It should be shipped in a well-protected box. I am selling only within the European Union (EU), no Malta or distant islands, and it is difficult to ship elsewhere. Thank you very much in advance.
