Norse text where snake briefly recalled (4)
I believe the answer is:
edda
'norse text' is the definition.
(I know that Edda is a type of norse text)
'snake briefly recalled' is the wordplay.
'snake' becomes 'adder' (type of snake).
'briefly' means to remove the last letter.
'recalled' is a reversal indicator (to recall can mean to bring something back).
'adder' with its final letter taken away is 'adde'.
'adde' reversed gives 'EDDA'.
'where' is the link.
(Other definitions for edda that I've seen before include "mythological book" , "Icelandic myth collection" , "Book of Icelandic poetry" , "Norse saga" , "Lots of old lines" .)
