M. Vitruvii Pollonis de architectura libri decem ad Caesarem Augustum omnibus omnium editionibus longe emendatiores collatis veteribus exemplis

An architect must be of great spirit, not arrogant, but approachable, fair, and faithful, and without greed. He must not be covetous, nor should he have a mind preoccupied with receiving gifts, but rather he should guard his own dignity with gravity, by maintaining a good reputation. When asked, he should undertake his duties, not ask for them himself.

A circular portrait depicts a man with a beard, wearing a cap and doublet; this is likely Guillaume Philandrier, the editor of this volume.

It is difficult to write of the form or the mind of Philander,
But his own work displays both things clearly.

This work contains the strength of genius and the spirit of Philander,
This image reflects the countenance of his body.
