Rise of Muse in Proust, as Mann, excited us (5,9)

I believe the answer is:

mount parnassus

I'm a little stuck... Click here to teach me more about this clue!

'rise of muse' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'proust as mann excited us' is the wordplay.
'excited' indicates an anagram.
'proust'+'as'+'mann'='proustasmann'
'proustasmann' with letters rearranged gives 'mountparnass'.
'mountparnass'+'us'='MOUNT PARNASSUS'

'in' is the link.

Can you help me to learn more?

(Another definition for mount parnassus that I've seen is " a rise in Greece".)

I've seen this clue in The Telegraph and The Times.
