## Fountain decoration excerpt

Clipped repeat:

(Not sure if I got the mosaic quite right. There were some damaged and replaced tiles that look a little out of place.)

## Screen pattern, Aga Khan Museum

I’m rather pleased with this, as it’s the first pattern I’ve worked out from a real example, a screen in the Aga Khan Museum:

Here’s the pattern as a full page PDF from Inkscape: akm-screen-tiled-strapwork.pdf. The pattern’s not much more than an 8-pointed star with a smaller 8-pointed star inside it, rotated 22½°. But it’s still kinda neat.

## Islamic Radial Geometric Design: SVG Templates for Inkscape

These SVG templates are modelled after Eric Broug‘s drawing templates for Islamic Geometric Design pattern elements. Although written for Inkscape, they should be usable with almost any graphics program.

By enabling snapping to nodes and object centres, your drawing program can act like an accurate straight edge and compass for constructing geometric figures.

## File Nomenclature

The files are name N-LL-S.svg, where:

• N — is the root symmetry: 4-fold, 5-fold, 6-fold, etc.
• LL — the total number of lines arranged evenly around the circle. This will always be a multiple of N.
• S — If the total number of lines has another symmetry that is a factor, this is S. If S = 0, then only the root symmetry is marked.

Examples:

1. `4-12-6.svg` — base symmetry 4-fold (square/diamond), with 12 lines or 30° spacing. Hexagonal (6-fold) guidelines are highlighted in a different colour.
2. `5-10-0.svg` — base symmetry 5-fold (pentagonal), with 10 lines or 36° spacing. No other guidelines are highlighted.

## Features

In Inkscape 0.91:

• units set to mm
• snapping set to cusp nodes, intersections, and object rotation centres
• construction lines on a separate layer (‘construction’) from the active layer (‘drawing’)
• templates are initially sized at 100 x 100 mm
• hair-line (0.1 mm) construction lines

WTFPL (srsly).

## Tidied-up edition of Bourgoin’s Arabic Geometrical Design sourcebook on archive.org

Just uploaded Les éléments de l’art arabe: Le trait des entrelacs by Jules Bourgoin (aka Arabic Geometrical Pattern & Design) to archive.org. This is much cleaned up from the Google Books scan, which had many duplicate pages and no metadata.

This is much better than the (now returned) Kindle edition
