I want to know the answer to the following question:
When did Constantinople fall to the Turks?
All the background I'm provided with is that "Meanwhile, in Renaissance Italy, a new period in the history of translation had opened in Florence with the arrival, at the court of Cosimo de' Medici, of the Byzantine scholar Georgius Gemistus Pletho shortly before the fall of Constantinople to the Turks (1453).". Is that enough to answer the question?
