Passes time in classical fashion (4)
I believe the answer is:
dies
'passes' is the definition.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for dies that I've seen before include "twenty-four hours in Rome" , "Berkshire racecourse" , "Ceases to be, cutters" , "one day in ancient Rome" , "Departs" .)
