The first French sculptor is not the first French sculptor known by his name, Gislebert of Autun, who in the 12th century sculpted statues in the cathedral
and signed his name Giselbertus there, yet whose name was actually found to be Violalet-de-Duc
Then, quite a standard thing for a temple is the name donor of the temple, the Burgundian Duke Gilbert.
However, the duke lived in the 10th century, and the temple belongs to the 12th, but here the situation is
the same as with the inscribed name of Marcus Vipsanius Agrippa on the Pantheon, signed with the dedication, rather than
the author. So, not everything is so simple.
