Mechanical equinoctial dials
Three examples of mechanical dials made in London in the first half of the 18th century. In each case, when the dial has been properly aligned with the meridian, adjusted for latitude and targeted on the sun, the time is given by the position of a pointer moving over a scale of hours.
