Universal equinoctial dial
Add to album

This universal portable equinoctial dial, a type of sundial, was made around 1820. It was sold by W. & S. Jones, scientific instrument retailers based in London.

The brass instrument is fitted with two levels and three levelling screws. It is inscribed 'W & S JONES/ 50 HOLBORN/ LONDON'. It is universal in the sense that it can be set up to any latitude on the hinged altitude arc.

Although this instrument would have been more expensive and less portable than a pocket watch, it was sufficiently beautiful and complicated to impress its owner's friends of his wealth and mathematical abilities.
