From John Julius Norwich’s More Christmas Crackers (1990):

Holorhymes are whole lines which have the same sound but different meanings. For some reason, they seem to go better in French. Louise de Vilmorin gave me two beautiful ones:

Étonnamment monotone et lasse
Est ton âme en mon automne, hélas!

And

Gall, amant de la reine, alla tour magnanime,
Gallament de l’arène à la Tour Magne, à Nîmes.

This second one is by Victor Hugo.
