Further on down from the hill from the sculpture of the hugging couple (“Reconciliation”), there’s a crouching woman on a plinth.
The inscription reads "Thrift is the gleaner behind all human effort". (A gleaner is someone who picks up grain left in the field by the harvesters.) And Googling for the inscription led to a single page containing a poem called Symbols by Stuart Butler.
Another bit of not-terribly-well-documented-or-explained history hidden in the middle of Stormont.
