Focus In the Koran, the holy book of Islam,
there are strong prohibitions against idolatry of any sort. Many of the early
leaders of Islam interpreted these statements as an injunction against the
representation of humans or animals in art. While this tradition may have
frustrated some Islamic artists, others took up the challenge and became the
greatest pattern makers of their time. Instead of covering buildings and other
surfaces with human figures, they developed complex, decorative patterns with
which to adorn palaces and mosques and other public places. Three types of
patterns were developed: designs derived from plant life; designs based on
calligraphy; and designs based on geometric shapes.
Islamic patterns emphasize five basic design principles.
1.
They are made up of a small number of repeated geometric
elements that create a complex whole by repeating a few elements.
2.
They are two dimensional both in form and intent. No
attempt is made to create a three dimensional effect or representation.
3.
They radiate symmetrically from a central point. Westerners
who attempt to "read" the art from left to right and top to bottom
often fail to see the whole work as intended by the artist.
4.
They are not designed to fit within a rectangular frame.
Unlike Western art which typically begins with a rectangular frame that is as
much a factor in the design of the work as any other element, Islamic art
begins with a central point and patterns that radiate from that point until
they encounter some barrier.
5.
They are constructed from patterns of circles.
For instance, using circles as a tool, a hexagon may be
constructed without resorting to measurement.
Tasks
1. Measure the sides of the hexagon. Are they all the same? Measure the angles of the hexagon. Are they all the same?
2. Surround the original hexagon with hexagons of the same size. Describe your strategy and list the distances and angles associated with the translations.
3. Do you think that the plane could be tiled with the hexagon? Explain your reasoning.
