The Tavola Ritonda, also known as ms. Palatino 556, is an excellent product of the culture of the Italian Po Valley Courts. The text, written in vernacular, offers an account of the main tales from the Arthurian cycle, including the Quest of the Holy Graal and the adventures of the knights of the Round Table, intertwined with the love stories of Lancelot and Guinevere, and Tristan and Isolde.
The manuscript bears the date 20th July 1446, and it was produced by the copyist Zuliano degli Anzoli and his workshop.
The iconographic apparatus is very rich, bearing 289 drawings, most of them executed in pen. The illustrations serve as a comment to the story told by the text.
The codex is today treasured at National Central Library of Florence.
