'in 1728' is the definition.
'great gross' can be an answer for '1728' (synonyms). I'm unsure of the 'in' bit.

'famous yet repulsive' is the wordplay.
'famous' becomes 'great' (I've seen this in another clue).
'yet repulsive' becomes 'gross' (I've seen this in another clue. I am not sure about the 'yet' bit.).
'great'+'gross'='GREAT GROSS'
