Venetian traveller (5,4)
I believe the answer is:
marco polo
'venetian traveller' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for marco polo that I've seen before include "Venetian merchant, who travelled to China" , "traveller in East" , "13th-century Venetian traveller" , "Historic trader" , "European traveller" .)
