                                Description"The sundial, set in the porch gable dates from circa 1900. Sundials or sun clocks are considered to be the oldest known device for the measurement of time and one of the most ancient scientific instruments. The oldest known true sundial was built around 1500BC in Egypt. Shaped like a letter 'L' the length of the shadow cast by the vertical leg along the horizontal leg indicated the time. The Romans perfected the horizontal sundial we know today and invented portable travelling versions." Photo by Maigheach-gheal, 2011.
