Summary

Description

Decorative pseudo-Celtic design of three figure-8 knots along a closed triangular loop. For an alternative version, see File:Three-figure8-knot_triang1.svg .

For a more complex "double-stranded" version of this basic pattern (not formed from straight lines and circular arcs, and not fitting exactly within an equilateral triangle), see File:Lindisfarne StJohn Knot2 3.svg ...
