An analysis of the unusual longitude inscription found on the St Mark’s, Longwood dial. By comparison with the Hawkshead dial, it is concluded that the inscription refers to the 'Plane’s Longitude,' which defines the longitude where the dial could be used horizontally, and is numerically equal to the hour angle between the substyle and noon lines.
