Dalmatic

Dalmatic, an ecclesiastical vestment somewhat like a surplice, but more richly embroidered, longer, and with round instead of pointed sleeves. It seems to have been first worn in Dalmatia, whence the name, and is mentioned as existing as early as A.D. 250. It was sometimes worn by mediaeval kings at their coronation, and Edward I. was buried in one of red silk. In the Anglican ritual it is the special vestment of the assistant ministers in the Holy Communion.
