No Mathe-mat-ics Required

What’s amazing is that even without advanced knowledge with mathematics, and without drawing plans on paper, weavers are able to create complex geometric designs by hand. These complex geometric designs depicts advanced levels of geometry and algebra using a combination of a weaving and counting technique.

Different finite designs and repeating patterns occurring in different Philippine ethnic communities are being studied today through the analysis of their symmetry groups and colored symmetrical structures.

Repeated patterns are basic discrete design elements and these symmetrical patterns (called a motif) are not only seen in mats, blankets, etc., it can be seen in our very own sablay!

A simple example of some of the symmetries in sablay: see those blue diamonds?  They are moving along a line. This kind of symmetry is called “translation” – a shift of the motif by a given distance in a line.

a/n: ang sayaaaa kaso di ko na kaya i-name yung ibang weave patterns/ symmetries sa sablay :(((
