Son of Adam said to sound archaic (4)

I believe the answer is:

seth

I believe this is a double definition.

'son of adam' is the first definition.
(I know that Seth father Adam)

'said to sound archaic' is the second definition.
(I've seen this before)

(Other definitions for seth that I've seen before include "Biblical character" , "One of the first men" , "Vikram --, Indian author" , "Adam's third son" , "god of Egypt" .)

I've seen this clue in The Globe and Mail.
