C8 Q36

It is committed against the anointed brought
from Saulne, Saint Aulbin and Bell'oeuvre
To pave with marble taken from distant towers,
not to resist Bleteram and his masterpiece.

Sera commis conte oingdre aduche
De Saulne et ſainct Aulbin et Bell'oeuure
Pauer de marbre de tours loing eſpluche
Non Bleteram reſiſter et chef d'oeuure.
