Engraving ('J. Harris Sculpt'), reproducing a mediaeval illustration, titled 'The Expedetion [sic] of Africa, undertaken by the Duke of Bourbon, as General in Chief, with several other English & French Knights, at the entreaty of the Genoese.'

On paper 25 x 20 cm. Plate size 14 x 18.5 cm. Uncoloured. Title beneath print and engraver's details beneath bottom right-hand corner. Image and text clear and intact. On aged, creased and foxed paper with wear and slight loss to extremities. The illustration shows a number of galleons at sea with wind-filled sails. Each is filled with knights whose flags and shields, each bearing different designs and coats of arms, are ranged along the sides. The National Maritime Museum possesses a coloured copy of this uncommon print, which also featured in the Hennin Collection. Harris was an engraver connected with the publisher Rudolph Ackermann. The Duke and the Genoese launched the expedition as a crusade against the Hafsids of Tunis, with the aim of suppressing piracy based in the city of Mahdia.
