Dear Reinhold,
Thank you for sharing that link http://www.cadrans-solaires.fr/cadrans-Londres-saint-margareth.html <http://www.cadrans-solaires.fr/cadrans-Londres-saint-margareth.html> and that picture of the fine St Margaret's, Westminster sundials. I believe they were designed by Chris Daniel and made by Brookbrae but am open to correction. Something about them which has always caused me to wonder is the absence of hours from about 6 to 8 a.m. and 4 to 6 p.m. on the North dial, which only shows hours before 6 a.m. and after 6 p.m. - not the whole time the Sun is to the North at midsummer. I can think of at least two possible reasons: - firstly, having the gnomon planted as it is in the ring, and near the edge, would make the space for them insignificantly small. - secondly, the projecting corner turrets of the church tower probably shade the dial until the Sun is some way North of due East or due West. The North gnomon could have been designed differently but would then be less like an inverted version of the South gnomon and this would reduce the overall symmetry. Of course, having also East and West dials means there is no shortage of somewhere to read the time during these hours. Can anyone comment on this?
