An uncommon sea chart of the south eastern portion of Ireland which was first published by William Mount and Thomas Page from at least 1729 in the ‘English Pilot First Part, Southern Navigation’. It extends along the east coast to include Dalkey Island at the approaches to Dublin Bay with a compass rose identifying north to the right. Which leads nicely to a large dominant inset of Dublin Bay and the city featured in plan. Hoath peninsula is easily recognised and North Bull is now a formally constructed island. The inner waters have been reclaimed by the Port of Dublin. The major ports and harbours of the coastline of Ireland are featured along with some soundings. Shirley ‘Atlases in the BL’ M.M&P 1b no. 9.
