Objects from barrows in Derbyshire

The objects shown are a polished stone axe found in November 1791 'in a romantic valley...where Mr Gell is now making a road from Hopton Moor to Ible', a pottery urn and the stone slab (with a Roman inscription) which covered it, from a barrow called 'Abbot's Low' near Hopton, and part of a horn found at Butterley.
