Аннотация:Few historians today would challenge the dictum that it was the development of Greek studies in the West that did more than any other single factor to enlarge and widen the intellectual horizon of the Italian Renaissance. The broad lines of this pattern of development are now reasonably well known, and scholars are devoting efforts rather to elucidating details in the transmission of Greek learning from Byzantium to Italy. Nevertheless, occasionally a document may be discovered that will not only provide new details but clarify an entire episode of capital importance in the development of Western Greek studies.
