09 Boxwood Compass
The wooden leaves of this surveying compass are simply but elegantly decorated and the silvered compass bowl is more elaborately engraved in a style characteristic of 18th-century London makers. Around the centre is the signature “I. COGGS. FLEET STREET: LONDON. Fecit.”
John Coggs was a member of the Pewterers Company but, under the rules of the London guild system, this placed no constraint on his actual trade, and he practised as a mathematical instrument maker and engraver. He is recorded as working from 1718 and his address was given in 1729 as the Globe & Sun over against St Dunstan’s Church in Fleet Street. In 1733 he went into partnership with one of his former apprentices William Wyeth, and this joint venture lasted until 1740.
