I wonder how to choose, I have more than a few a few books on this theme. There are technical books written as first introduction and therefore very general, and there are specialist books on every aspect of square rigger sailing - use of the sextant, laws of storms, distances and trade winds, stowage, sail making, rigging, practical seamanship and the duties of watch officers. On the keeping of discipline, and of suitable sermons, of knots and splices, and on shipbuilding theoretical and practical, laying off, dimensions, materials and on shipbuilding nomenclature, books very old and quite new, books both thin and voluminous, tomes illustrated and not. I might mention a few that will cost you a bit of money to acquire, some because of content and some because of their rarity. Some that are easily obtained in English French and German, and some that can be of interst only for the few Norwegian language users here. And I might suggest one on shipbuilding in Latin as well – although I have not read that one. However, there is a compilation of supposed excellence in pictures, poetry and stories on the theme of square sail titled "In praise of Sailors" compiled and edited by one Herbert Warden the third and published in New York for the first time in 1978. And I do not think anyone will be wholly unimpressed by this book made intently to impress the impressionable. Writers include all the big names the editor could find, such as Conrad, Masefield, Marryat, Melville, Kipling, Swinburne, Whitman and Longfellow and even a few pure sea-writers like Riesenberg, Hubert Shaw and Dana. Among the artists you will find Spurling, Brangwyn, Briscoe, Dawson, Fischer, Grant, Leavitt, Wilkinson - and a even few famous painters of dubious connection with the sea, like like Toulouse Lautrec and Zorn. ...But seriously, Conrad is always damn good! :sweat:
