Description
Rare brass surveyor’s square in its case, signed “Dominicus Lusuerg F. Romae 1724”, case marked G A. Rome, Italy, 1724.
Brass surveyor’s square of a spherical shape with 8 slots ending in a turned knob.
The tubular base allows it to be attached to a surveying stand which was usually a wooden stick. The signature “Dominicus Lusuerg F. Romae 1724” is engraved on top of the sphere just above the slots.
The turned wooden case opens in two parts and the truncated cone-shaped lid has a riveted metal frame around its largest diameter.
The interior is made of raw wood and this case is stamped three times with the mark G A, once at the top of the lid and twice under the base (see photos at the end). Very good condition with its original case.
Surveyors’ squares signed by Lusuerg are extremely rare and those with original cases even rarer, as these have often been lost or destroyed by time.
Maker: Dominicus Lusuerg (active from 1691 to 1744), son of Jacobus Lusuerg (active from 1668 to 1791), was a renowned Italian manufacturer who also worked with his father. The Lusuergs made a large number of mathematical instruments, always of exceptional quality, as can still be seen in many museums, including the Galileo in Florence and the Science Museum in London.
Reference: To our knowledge, there are no surveyors’ squares in public collections and only one other surveyor’s square signed Lusuerg is known to be in a private collection.
Dimensions:
– square : height of 14.7 cm x diameter of 5.8 cm
– case : height of 18.0 cm x diameter of 6.8 cm
Rome (Italy) dated 1724.
