Provenance:The Leonard Fuller Collection. John Rowley is recorded in Clifton, Gloria Directory of British Scientific Instrument Makers 1550-1851 as a mathematical instrument maker and book engraver working from 'Behind the Exchange' Threadneedle Street, London in 1691, then from 'The Globe under St. Dunstan's Church' Fleet Street 1702-15 and at Johnson's Court, Fleet Street 1710-27; Clifton noted that the latter address may well have been his living residence. Amongst Rowley's apprentices was Thomas Wright (in 1707) who then went on to become his successor and one of the most important makers of scientific instrument makers of the eighteenth century. Another apprentice was John Coggs who went on to become particularly well known for his sundials, most notably his universal ring dials. This design of portable pocket sundial was devised by Michael Butterfield, an English Instrument maker who settled in Paris around 1685. Although this type of dial became popular with other French makers (most notably those who worked nearby to Butterfield's workshop on 'Le Quay de L'Horloge') very few appear to have been made by English makers in London; hence the present lot is a particularly rare example.
