In this two part series we will draw two geometric patterns featured on the South facing facade of theCatedral de Santa María de la Sede de Sevillanamed The "Puerta del Príncipe"~ The Door Of The Prince ~

There are 15 doors on the cathedral’s four facades and each one features a unique relief carving.

We will explore gothic tracery using only a compass and ruler, freehand biomorphic movements and learn rendering skills using pen and graphite.
