Colard Mansion, Dialogue des creatures : un second manuscrit, pour quoi faire?

Pierre Ruelle, editor in 1985 of the Dialogue des Creatures translated by Colard Mansion (1482), had at his disposal only the manuscript housed at the ÖNB in Vienna; the relatively recent discovery of the second manuscript (in a private collection) made it possible to undertake an exhaustive collation, revealing that (1) the Vienna copy transmits a text of inferior quality, (2) the two manuscripts derive from a common antigraph, (3) the errors of the Vienna manuscript can be attributed in most cases to the copyist, not to the translator
