Traditionally framed in a gilt mid 19th C surround, this was originally a lighthouse reflecting lens dating from 1916.
Acid etched by the makers Chance Brothers with patent, serial number and focus measurements, the condition is exceptional. The distortion in this concave parabolic reflector is complex; from different points and distances it changes dramatically. Viewed from close quarters it brings the viewer into focus with an intense clarity of definition, at a distance there is an unusual dimensional bounce difficult to describe without standing in front of the object. The reflection also sometimes gives the illusion of circular ripples in water.
At 75cm diameter overall it was used as a hall mirror in Slane Castle in Ireland.
An inspired combination of precision and tradition.
