Grecian vessel (3)
I believe the answer is:
urn
'grecian vessel' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for urn that I've seen before include "Vessel for making hot drinks" , "Spore-producing capsule of a moss" , "Rounded vase" , "Run to get large jar" , "Funerary vessel" .)
