File:Early Medieval great square-headed brooch fragment (FindID 270270).jpg

English: A fragment of a great square-headed brooch of 6th century date, made of cast and gilded copper alloy. The fragment is probably the terminal (or possibly the side knob) of the footplate of the brooch. It is sub-circular in plan with a decorated front and undecorated reverse. Very small (less than 1mm in size) traces of gilding remain on the front, which is decorated with a border separated into rectangular panels of relief decoration in angular S-shapes, which may be Style I beasts or parts thereof. An undecorated band separates the border from the central decoration of the terminal, which consists of a human mask made up of a pelta shape (forming the forehead and nose) with five vertical ridges running upwards from the top of the pelta. The human mask on terminal or side lobe is found on a handful of Hines groups, but there is only one small group with this vertical reeding extending from the nose and Style I decoration around the head - Group XXII. It is therefore likely that this lobe belonged to a Group XXII brooch; these brooches have a northerly distribution and occur in Hines's Phases 2 and 3, 510-570.
