Codex Berinensis,a Florentine copy of an ancient Roman medical treatise, is undated but contains clues to when it was produced. Its first 80 pages are by a single copiest, but the remaining 20 pages are by three different copiests,which indicates some significant disruption .Since a letter in handwriting identified as that of the fourth copiest mentions a plague that killed many people in Florence in 1148, Codex Berinensis was probably produced in that year.
