Rhodes, Michael, "A pair of fifteenth-century spectacle frames from the City of London", The Antiquaries Journal, 62/1 (1982), 57-73, il·l.
- Resum
- The riveted spectacle frames from excavations at Trig Lane (City of London) in 1974-1975 are the earliest from a deposit of known date (ca. 1440). Their method of construction, from two bull metacarpal bones, is suggested, and their form compared with contemporary representations and the only other surviving examples from convent at Wienhausen (14th c.). Their possible mode of use is deduced from constructional details, contemporary illustrations and literary sources. A cluster of pinholes at the rim ends of both handles were probably intended to extend the field of view, acting as simple lenses, and as such probably represent the earliest European evidence of the utilization of pinholes in an optical instrument. There follows a survey of English medieval documentary references to spectacles which indicates that the Dutch spectacle industry had a vital influence upon developments in England. It is likely that the Trig Lane spectacles were imported from the Low Countries, or made by a craftsman from the Low Countries working in London. Includes photographs and diagrams of the frames found and an appendix by Philip Armitage on the source of the bone material used in the manufacture of the spectacles.
