Online Courses (Live sessions - recorded)
Level
Advanced: It is necessary to have a basic knowledge of geometric drawing and some precision in tracing.
Duration
10h (4 sessions of 2h30)
About the Pattern
Rose windows vary in shapes. Some of them really look like flowers with petals radiating from a centre. It is the case for the splendid western rose from Our Lady of Strasbourg (France). Those petal shapes come directly from the shapes of pointed arches used in gothic architecture.
Course Content
This course was recorded live, more than a year ago, and my recording quality has improved since, hence the reduced priced.
I might do a new version of it at some point.
In this 4 sessions online course, we will therefore start by an introduction to different arch shapes. Then we will see some basic elements of gothic architecture, the foils (little flower like shapes with a varied number of petals) before combining all those elements to trace the large rose.
The western rose from Our Lady of Strasbourg is made of 16 large petals, we will therefore see how to divide a circle in a multiple of 8. We will also see how to divide a circle in 5 because Strasbourg cathedral show many examples of this symmetry, including in the western rose details.
All will be traced using compasses and straight edge, using logic principles of geometry, similar to those used by cathedral builders.
