An illustrated talk by
Wednesday 14th October 2015
at 7.30 pm
EMMTEC Lecture Theatre, Brayford Pool Campus, University of Lincoln
The tracery (stonework) of mediaeval Decorated windows (c. 1250 – 1350) may not seem an obvious area for mathematical exploration but the speaker has been doing that on and off for over 20 years and will share some of his discoveries in this illustrated lecture. The topics will include:
- The names that are used today for styles (e.g.
Geometric, Intersecting and Reticulated) are 19th century
inventions and not well defined.
- Classification rules using only visual properties, not
metric ones, will be introduced and how they lead to an
understanding of the geometry needed for construction and
constraints of the architects.
- Qualitatively it appeared likely that in some windows
of the Flowing style what appear at first sight to be simple
circular arcs must change radius at some point. The advent
of digital cameras and simple programming has sorted this
and other interesting results discovered.
