TIES.--The principal references to early Britain in classical
writers occur in Strabo, Diodorus, Julius Caesar, the elder Pliny, Tacitus,
Ptolemy and Cassius Dio, and in the lists of the Antonine Itinerary
(probably about A.D. 210-230; ed. Parthey, 1848), the _Notitia Dignitatum_
(about A.D. 400; ed. Seeck, 1876), and the Ravennas (7th-century
_rechauffe_; ed. Parthey 1860). The chief passages are collected in
Petrie's _Monumenta Hist. Britann._ (1848), and (alphabetically) in
Holder's _Altkeltische Sprachschatz_ (1896-1908). The Roman inscriptions
have been collected by Huebner, _Corpus Inscriptionum Latin._ vii. (1873),
and in supplements by Huebner and Haverfield in the periodical _Ephemeris
epigraphica_; see also Huebner, _Inscript. Britann. Christianae_ (1876, now
out of date), and J. Rhys on Pictish, &c., inscriptions, _Proceedings Soc.
Antiq. Scotland_, xxvi., xxxii.

Of modern works the best summary for Roman Britain and for Caesar's
invasions is T.R. Holmes, _Ancient Britain_ (1907), who cites numerous
authorities. See also Sir John Evans, _Stone Implements, [v.04 p.0589]
Bronze Implements_, and _Ancient British Coins_ (with suppl.); Boyd
Dawkins, _Early Man in Britain_ (1880); J. Rhys, _Celtic Britain_ (3rd ed.,
1904). For late Celtic art see J.M. Kemble and A.W. Franks' _Horae Ferales_
(1863), and Arthur J. Evans in _Archaeologia_, vols. lii.-lv. Celtic
ethnology and philology (see CELT) are still in the "age of discussion."
For ancient earthworks see A. Hadrian Allcroft, _Earthwork of England_
(1909).

For Roman Britain see, in general, Prof. F. Haverfield, _The Romanization
of Roman Britain_ (Oxford, 1906), and his articles in the _Victoria County
History_; also the chapter in Mommsen's _Roman Provinces_; and an article
in the _Edinburgh Review_, 1899. For the wall of Hadrian see John Hodgson,
_History of Northumberland_ (1840); J.C. Bruce, _Roman Wall_ (3rd ed.,
1867); reports of excavations by Haverfield in the _Cumberland
Archaeological Society Transactions_ (1894-1904); and R.C. Bosanquet,
_Roman Camp at Housesteads_ (Newcastle, 1904). For the Scottish Excavations
see _Proceedings of the Society of Antiquaries of Scotland_, xx.-xl., and
especially J. Macdonald, _Bar Hill_ (reprint, Glasgow, 1906). For other
forts see R.S. Ferguson, _Cumberland Arch. Soc. Trans._ xii., on Hardknott;
and J. Ward, _Roman Fort of Gellygaer_ (London, 1903). For the Roman
occupation of Scotland see Haverfield in _Antonine Wal
