What is "shabaka"

Neferkare Shabaka (or Shabako) was a Kushite pharaoh of the Twenty-fifth dynasty of Egypt, who reigned from 721 BC–707/706 BC.

Shabaka are stained glass windows made by national Azerbaijani masters, without glue or nails.

Shabaka fill walls and window openings of halls and rooms in the Palace of Shaki Khans. Geometric patterns of shabaka-windows harmonize with the general composition of the palace’s façade. Stained-glass windows of central halls and side rooms open on the façade. These stained glass windows are the special feature in the palace’s architecture.
