Renault of Montauban
In the last chapter of the romance of Aymon's Four Sons, Renault, as an act of penance, carries the hods of mortar for the building of St. Peter's, at Cologne.
“Since I cannot improve our architecture, ... I am resolved to do
like Renault of Montauhan, and I will wait on the masons. ... As it was
not in my good luck to be cut out for one of them. I will live and die
the admirer of their divine writings.” —
