Shash - Headgear of the Chaldean Catholic Clergy

The shash (شاش) is worn by the Patriarch of Babylon of the Chaldeans and Primate of the Chaldean Catholic Church during the liturgy and during everday life together with the cassock.
Shash (شاش) means muslin, gauze.

The shash consits of two parts:

(1) a round cylindrical "tarboosh" (fez), clad in bright red if the patriarch has the rank of a cardinal and in burgandy (wine red) if he is the rank of a bishop.

and

(2) windings of the black gauze which is made in such a way that the 7 edges become lightly visible. At the top of the sash is fixed a bundle of black threads (6.5 cm long in total) and these are fixed at the back side behind the gauze.

The 7 edges are in remembrance of the 7 days of creation, the 7 sacraments, the 7 gifts of the Holy Ghost, the 7 petitions in the Lord's Prayer as well as the figure 7 seen in the Book of Revelation (cf. Rev. 4:5).
