NO COPY LOCATED IN STC (861.6): "The copy formerly belonging to Henry Taylor was sold in 1955 and cannot be traced." Copies of the first edition of Speculum Nauticum, (London: Printed by T. Harper, 1624) were in the Phillipps & Robinson Trust collection (sale, Sotheby's London, 26 November 1973, lot 2244) and the Harrison Horblit collection (sale, Sotheby's London, 10 June 1974, lot 59); both lacked the colophon leaf. A "second edition corrected" was printed by Harper for Hurlock in 1632 (STC 861.3, locating just two copies, both in England). The Horblit sale catalogue notes (to the seventh edition, of 1668, lot 60): "All editions are rare, and the second, third and eighth seem to have disappeared altogether." A very influential book: the first edition was one of eleven works recommended to young seamen by Captain John Smith.
