This is the much rarer and earlier of two charts of the Harbour of Cork published by the firm Mount and Page. It was replaced at the latest by another in 1729. This particular sea chart was first published by William Mount and Thomas Page from at least 1701 in the ‘English Pilot First Part, Southern Navigation’. It focuses entirely on the city of Cork and its approaches. There is unusually for a sea chart, extensive topographical detail including numerous roads and outlying villages. The main road (E30) from Cork to ‘Midleton’ is clearly depicted. There are extensive soundings in many harbours and inlets. Sanderson (1971) 423 no. 76;Shirley (2004) M.M&P 1a no. 18.
