Far-seeing man who fell foul of the Inquisition (7)
I believe the answer is:
galileo
'foul of the inquisition' is the definition.
The definition suggests a singular noun which matches the answer.
'far-seeing man who fell' is the wordplay.
I cannot really understand how this works, but
'man' could be 'leo' (I've seen this before) and 'leo' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for galileo that I've seen before include "Famous scientist" , "He said Eppur si muove (But it does move)" , "Sixteenth and seventeenth century Italian astronomer tried for heresy" , "Refracting telescope inventor" , "Famous Italian" .)
