Line written up about fool and prophetess (9)
I believe the answer is:
cassandra
This clue could be a double definition.
'line written up about fool' is the first definition.
The definition suggests a singular noun which matches the answer.
'prophetess' is the second definition.
(I have seen 'Unheeded prophetess' mean 'cassandra' so perhaps 'prophetess' could also mean 'cassandra')
'and' is the link.
Can you help me to learn more?
(Other definitions for cassandra that I've seen before include "one having gloomy views" , "Prophesier of disaster" , "Prophet of doom" , "Prophetess during the Trojan War whose predictions were true but never believed" , "One who phrophesies disaster, named after ancient Greek woman" .)
