I recently bought a copy of d'Ailly. The first volume contains the following
inscription (approximate): "au
musee de gesuitet de
lyon, hommage et souveneir du l'auteur " (machine more or less translates as "To the Jesuit Museum of
Lyon, homage and recollection of the author"), followed by "Baron d'Ailly". Would this be an
inscription from d'Ailly or just celebrating him? (The museum appears to have covered a previous
collection mark on the title page of each volume, but I need a sunnier day to try to see through this to see what the mark is.)
