New angle on an ancient physician (5)

I believe the answer is:

galen

'an ancient physician' is the definition.
(I've seen this in another clue)

'new angle' is the wordplay.
'new' indicates an anagram.
'angle' with letters rearranged gives 'GALEN'.

'on' is the link.

(Another definition for galen that I've seen is " Ancient Greek anatomist, d.199 - angel (anag)".)

I've seen this clue in The Globe and Mail.
