Antique brass and steel dividers of unusually large dimension, dating to the mid-17th century

Country of manufacture


Categories: Maritime, Drawing Instruments


A massive and fine pair of 17th century brass and steel dividers. Probably Dutch or German, these were used for scribing measurements  or chart reading. The hexagonal head supported by deeply profiled mouldings is typical of early dividers of the period. The 5-leaf joint opens and closes perfectly. A hallmark in the shape of a horizontal “I” can be seen inside one leg.

In original condition with dings and dents commensurate with age. A spectacular piece for its sheer size and weight, see last 3 photos for scale.

24.5 cm / 9.7 inches.

A very similar example with the same hallmark is in the Harvard collection of scientific instruments:
