Portable equatorial or equinoctical sundial 1701

Dominicus Lusuerg, a Dutch artist active in the early 18th century, crafted this intricate portable equatorial sundial in 1701. The small brass instrument, housed in the Metropolitan Museum of Art, features a compass, a gnomon (a pin that casts a shadow to tell the time), and an intricate design engraved on the base. This type of sundial was designed to be used in any location on Earth, as it could be adjusted to account for different latitudes. The engraved details and intricate construction demonstrate the high level of craftsmanship and scientific understanding of the period.
