 The sources of the two illustrations of Sydney Cove and the Aboriginal group are not known . The ceramic colouring bears a general resemblance to contemporary Sydney Cove images which implies that an original watercolour or hand coloured engraving was used for copying rather than black and white images . In the case of the Library punchbowl , the depiction of Sydney Cove is most likely done from an engraving after a now lost drawing by Lewin , which may date to 1814 . This Sydney Cove engraving appeared as a full @-@ page illustration in the second edition of A Statistical , Historical and Political Description of New South Wales and its dependent settlements in Van Diemen 's Land etc ( London , 1820 ) by Wentworth , with a later , smaller , version as one of ten Port Jackson harbour views illustrated on Map of Part of New South Wales ( London , 1825 ) by publisher and engraver , Joseph Cross . As Australia 's first professional artist , Lewin produced many paintings for Macquarie and his senior officers . He also made a number of commissions for Riley . Lewin had a close association with Antill and both were part of Governor Macquarie 's 50 @-@ strong excursion party to inspect land and the new road over the Blue Mountains from 25 April to 19 May 1815 . The road had been built by convicts in 1814 , after the first European crossing by Gregory Blaxland , William Lawson and Wentworth in May 1813 .
