The bronze brooch illustrated from photographs on pl. xi (and here also from drawings by Mr. F. Cottrill), was found a number of years ago by Mr. T. W. Armitage of Trent Lock, Long Eaton, on the high ground known as Red Hill, above the steep right bank of the river Soar just south of its confluence with the Trent in southern Nottinghamshire, between the villages of Thrumpton and Ratcliffe-upon-Soar and on the west side of the main L.M.S. railway line from Leicester to Nottingham, Long Eaton, and Derby. The site is habitually arable land, and Mr. Armitage has collected a number of antiquities from its surface, including besides this brooch several Roman coins and Romano-British bronze brooches along with some amount of mainly Romano-British pottery, to which, in the winter of 1943, he drew the attention of the Society. In subsequent correspondence he readily gave permission for the publication here of this unusual brooch, which he had himself recognized as a Celtic product of the pre-Roman Iron Age; and in lending it to the present writers for the purpose, he allowed it also to be cleaned and examined at Oxford, under Mr. Jacobsthal's direction, by Mr. V. R. Rickard in the laboratory of the Ashmolean Museum. The photographs were taken in the studio of the same museum.
