Upton, (Wirral), 1st.ed., 2005. 171 pp., profusely illustrated in full colour. D.j., 32 x 24cm. MINT. The late Dr. Davidson completes a trilogy providing an integrated, topographical and historical account of the 19th century square-riggers and marine artists of North West Britain – The Mersey, Clyde, and now Northern Ireland. This work includes previously unpublished personal and family details of Joseph Semple of Belfast, with a catalogue raisonné of more than 50 of his paintings. The work of lesser-known marine artists are also covered. The author’s unique account of the evolution and practical operation of the three main mercantile marine Flag Codes, first published in his ‘Liverpool’ work in 1986 (See No. 80 above) is extensively updated here, with illustrative examples being produced in colour throughout the book. Appendices provide a comprehensive key to Watson’s and Marryat’s Ship Numbers (the latter includes a copy of the temporary ‘Supplement’ in the extremely rare 7th edition of 1840) and the book contains a wealth of information for those interested in flag codes, marine art, square-riggers and early steamships.
