Glyph

Glyphs are symbols on the stargates which the chevrons lock onto. Glyphs are what the stargate uses to dial. The basis for glyphs are star constellations. Also, there are several differences between Milky Way and Pegasus galaxy glyphs:

Milky Way glyphs are:

-Represented as figures

-Mounted on a spinning wheel

-Made out of metal and raised above the surface of the wheel

Pegasus glyphs are:

-Represented as dots connected by lines

-Displayed electronically and appear in sequence instead of spinning
