The apartment of Julius II,
known as the Stanze di Giulio II

The first Stanza to be frescoed was that of the Segnatura.
At that time neo-Platonism had emerged in the papal court
and the Stanza della Segnatura represents
the categories of Neoplatonism:

the True, the Beautiful and the Good.

In the vault of the room we see the metaphors of
the Theological True, the Philosophical True,
the Beautiful and the Good.
