Table of contents: title: Describes single handed dividers found at a Scottish archaeological site, and dating to 1685. The conventional  design is of a type associated with use on nautical charts, with a decorated version illustrated on the title page of Spigehel der Zeervaerdt of 1584, and the English edition Mariner’s Mirror of 1588. Draws attention to the fact that the version of that title page made for the cover of the Journal of the Society of Nautical Research, incorporates an anachronism, showing single handed dividers as made in the 20th century!
