_History._--The early history of Caithness may, to some extent, be traced
in the character of its remains and its local nomenclature. Picts' houses,
still fairly numerous, Norwegian names and Danish mounds attest that these
peoples displaced each other in turn, and the number and strength of the
fortified keeps show that its annals include the usual feuds, assaults and
reprisals. Circles of standing stones, as at Stemster Loch and Bower, and
the ruins of Roman Catholic chapels and places of pilgrimage in almost
every district, illustrate the changes which have come over its
ecclesiastical condition. The most important remains are those of Bucholie
Castle, Girnigo Castle, and the tower of Keiss; and, on the S.E. coast, the
castles of Clyth, Swiney, Forse, Laveron, Knockinnon, Berriedale, Achastle
and Dunbeath, the last of which is romantically situated on a detached
stack of sandstone rock. About six miles from Thurso stand the ruins of
Braal Castle, the residence of the ancient bishops of Caithness. On the
coast of the Pentland Firth, 11/2 miles west of Dunscansbay Head, is the site
of John o' Groat's house.

CAIUS or GAIUS, pope from 283 to 296, was the son of Gaius, or of
Concordius, a relative of the emperor Diocletian, and became pope on the
17th of December 283. His tomb, with the original epitaph, was discovered
in the cemetery of Calixtus and in it the ring with which he used to seal
his letters (see Arringhi, _Roma subterr._, l. iv. _c._ xlviii. p. 426). He
died in 296.
