The force of the Taccola comparisons has given me the sense the 1420 mean from the carbon date might be off. I agree not enough to get us over into the 1500s, and other lines of evidence have put the manuscript closer to 1420, but certainly enough to wonder how confident I should be about the 95% confidence interval in the findings. I am aware that it could be an early copy, or share a source, and then we would not have to rethink those dates. But it does strike me that 1438 (the top of the confidence interval) would be considered an early date for Taccola copies if extant copies were our anchor point and not the carbon dating instead.
