Person setting up in coalpit, working with earth in the centre? (9)
I believe the answer is:
ptolemaic
'person setting' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I don't see?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for ptolemaic that I've seen before include "having old-fashioned ideas about the stars?" , "about astronomical theory" , "Dealing with heavenly bodies" , "such as Cleopatra" .)
