The complex geometry of Islamic design - Eric Broug

Islamic geometric design, developed since the 8th century CE, creates intricate patterns using only a compass and ruler by starting with a circle divided into equal sections (typically four, five, or six), drawing construction lines, selecting specific line segments to form a tile, and then tessellating (repeating) this tile across a grid; patterns with fourfold symmetry fit square grids, sixfold symmetry fits hexagonal grids, while fivefold patterns are more challenging to tessellate because pe

• Why this video: Author and pattern designer Eric Broug explains the structural rules of Islamic geometric design. He demonstrates how highly intricate patterns are built using only a compass and straightedge, illustrating how fourfold, fivefold, and sixfold symmetry form the basis of grid-based designs.

• Knowledge Checkpoint:

  • Explain how a circle acts as the starting point for all classical Islamic geometric patterns.
  • Differentiate between grid types based on fourfold, fivefold, and sixfold divisions.

Sacred Geometry – Dr Keith Critchlow

Sacred geometry uses dividers (compasses) as a spiritual tool where the top part symbolizes God's eye, one leg represents the direct connection from God to creation, and the other leg enables variation; Islamic geometric patterns emerge from regular polygons (triangle, square, pentagon, hexagon, heptagon, octagon, nonagon) by finding the balancing point (bazak) at their midpoints, creating the distinctive symmetrical designs found in Islamic art and architecture.

@CambridgeCentralMosque · 05:24

• Why this video: Renowned scholar Dr. Keith Critchlow outlines the spiritual and philosophical significance of geometry in Islamic art. He explains how the compass serves as a symbolic bridge: the stationary leg represents the divine center (unity), while the moving leg traces out the physical universe (multiplicity).

• Knowledge Checkpoint:

  • Connect the structural parts of a drawing compass to Islamic philosophical ideas of divine unity (Tawhid).
  • Explain why human or animal representations are avoided in sacred Islamic spaces in favor of geometry and calligraphy.

How to use Qalam for Arabic Calligraphy

@QalamAurKagaz13:2246,874

How to use Qalam for Arabic Calligraphy

In Arabic calligraphy, proper column holding involves holding it like a pen with the hand pointing to the top-left corner of the paper, the taller nib part pointing away from you, and the shorter part toward your left shoulder at an 80-degree angle. To create thinner strokes, move the column at the same angle as the impact (70-80 degrees), while thicker strokes result from moving the column at a different angle, utilizing the varying lengths of the nib's edges.
