as military in function and therefore ascribed them to him. Another suggested origin of Grim may be in the Celtic name Grin or Gryn (Gryan in Irish, a putative origin of the name Ryan), a signifier of the Sun as a divinity. The identities of Wōden and the Devil have also become conflated, as evidenced in the number of earthworks named after the Devil. As the Anglo-Saxon population converted to the new religion of Christianity, baptised converts renounced the old Saxon Gods along with the works of the Devil. It is thought that, as a result of this Christianisation, place names and features once associated with pre-Christian deities then came to be associated with the Devil. The names Grim, Graeme and Graham are closely connected and many British family and place names have been linked with the etymology of Wōden/Grim/Devil: Grimsby (residence of the Devil), Grimsthorpe (Village of the Devil), Grimshaw (the Devil's Wood), reflected in the use of dragon emblems in heraldry associated with Grim- names. Earthworks bearing names related to Grim or the Devil proliferate around Britain: Grim's Ditches exist in Berkshire, Buckinghamshire, Hampshire, Hertfordshire, Oxfordshire and West Yorkshire, and Devil's Dykes exist in Sussex, Cambridgeshire, Norfolk (near Weeting) and Hertfordshire. The Antonine Wall which once separated Scotland from Roman Britain is also sometimes known as Graham's Dyke. In Suffolk, a large Neolithic flint mine is known by the name of Grimes Graves. Beyond Britain, a set of Roman Limes on the borders of Hungary, Romania and Serbia are sometimes known as the Devil's Dykes in Hungarian. Berkshire Grim's Bank in West Berkshire runs for from inside the Atomic Weapons Establishment in Aldermaston, through Ufton Park woods to Ufton Nervet village. At Park Piece there are number of earthworks and Grim's Bank changes direction or may be a separate monument. Excavations in 1978 suggested there were two different earthworks and were most likely to be Iron Age in date. These two parts of Grim's Bank are referred to as Grim's Bank I and Grim's Bank II. There is another Grim's Bank running south of Aldworth and Streatley. Excavations have shown that the ditch is not earlier than the third century AD. Buckinghamshire There are three sections of the Chiltern Grim's Ditch in Buckinghamshire: A substations section from Park Wood to Hampden House Missenden Valley to the Lea From King's Ash to county boundary where it continues into Hertfordshire
