Who are the god and goddess in niches at left and right?

How can I know what niches you are talking about? Where are those? In the town hall of your home town? In the Parthenon temple in Athens?

Or, may I make a bold guess? In Raphael's painting 'The School of Athens'.

In that painting there are two niches with statues in the background.
They are to the left Apollo and to the right Athena.
