Abstract
In this paper we will examine the role of geometry in selected examples of art and architecture from
selected regions of the Western World. We will start from the Byzantine Empire. In the beginning we
will briefly look at the role of geometry in Byzantine architecture and architectural decorations. Then
we will explore other types of architectural decorations where geometry was used while creating
these decorations. We will examine selected Cosmati designs in Roman architecture and then we will
show the geometry behind the Gothic tracery (part 2 of this paper). Most of the designs discussed in
this paper are based on circular and interlaced shapes. We will show how these designs were
created. We will use Geometer’s Sketchpad to recreate them.
