This birds eye plan and view of Gibraltar was first published in Thomas Salmon’s ‘Modern History’ in the thirteenth volume. Many of the maps for this work begun in 1725 were engraved by Herman Moll. He was however to die in 1732 the year following this volumes’ publication which might indicate why this does not appear to be by his hand. Indeed this plate itself is not included in any later issue. Many of the copperplates for this work were included in later Salmon and Moll publications. This example however bears the RARE IMPRINT of Robert Sayer and William Herbert (1718-95). Herbert set up business on London Bridge in 1748 and was an unhappy viewer of its demise at the hand of a fire in 1758. This places the date of issue of this work as c.1755 and as yet from an unidentified source or separately published. It bears two insets in the lower corners of a chart displaying the route from England to Gibraltar and one of the Bay of Gibraltar. Between these are two tables on ‘Remarks on the Takeing Gibralter by the English’ and ‘Explaination of ye Seige by the Spaniards’. Beneath the latter appears the imprint of Sayer and Herbert.
