Goddess reportedly in chains (5)

I believe the answer is:

ceres

I'm a little stuck... Click here to teach me more about this clue!

'goddess' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for ceres that I've seen before include "Roman goddess; dwarf planet" , "Dwarf planet; goddess of agriculture" , "Corn-goddess" , "Roman goddess of corn" , "Head of agriculture" .)

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