This is a mirror for the website curvalinea.net. I have included a list of some of my papers, some photographs with spiritual, (a catalogue of major medieval European
buildings) sublime and harmonious dimensions, with  related archeological contexts (a list of European castles). There are also some photos of light which are connected
to a series of scientific experiments. The main page of curveline can be found here (more information on medieval art). The following version of my book is in prepublished
 format, and may alter slightly in the meantime; Christian Geometry:The Geometry of Light. It is a precursor to a forthcoming one, about Physics. If you would like to find
out more about my work, my name is Tristram de Piro and you can write, or send me an email, I would be very happy to receive any comments or suggestions. Any
 donations made towards the upkeep and development of  this research would be greatly appreciated. I am also interested in religious history and Neo-Gothic architecture
 in the USA and Britain. I tutor undergraduate or A-level mathematics, physics and chemistry online via Skype, this is my card, please contact me if you are interested in
having lessons. I'm starting a page on medieval painting and sculpture and a page on chess.
