Sea chart of Dublin Bay from the first English sea-atlas

A sea chart of Dublin Bay, marking the sand banks, with Howth and the streets of Dublin city shown. The chart was published in Collins' 'Great Britain's Coasting Pilot, being a New Survey of the Sea Coast', the first English sea-atlas based on personal survey. Undertaken on the orders of Charles II, Collins started his survey in 1681, a task that lasted seven years. The complete atlas was finally completed in 1693, and was so popular that editions were released, with only occasional revisions, until 1792.
