The etymology of Caledonia has not been satisfactorily explained. The celebrated James Macpherson explains it as follows:—“When South Britain yielded to the power of the Romans, the unconquered nations to the north of the province were distinguished by the name of Caledonians. From their very name, it appears that they were of those Gauls, who possessed themselves originally of Britain. It is compounded of two Celtic words, Gael, signifying Celts or Gauls, and Dun or Don, a hill; so that Gael don, or Caledonians, is as much as to say Celts of the hill country.” In the very next sentence Macpherson unconsciously suggests quite a different and better etymology: “The Highlanders to this day call themselves Gael, their language Gaelic or Galic, and their country Gaeldoch, which the Romans softened into Caledonia.” Consideration for Latin Inflections would readily transform Caeldachd into Caledonia. A rival explanation has found place in many school books—Coille-daoine, rendered Men of the Wood. This, however, is not the accurate translation. The compound is absurd and unnatural. It reads to a Gael like Men-Wood in English. Another explanation has been Gaedhil dhonna, brown-haired Gaels; but physiological facts and the laws of phonology do not support this derivation. The Welsh have given us its meaning from a Cymric standpoint; and as the word is unknown in Gaelic in its historic form the Welsh suggestions appear very reasonable. The Caledonian Forest in Welsh has always been Calydin or Celydin, a term which means Wood. Its Gaelic cognate would be Coilltean, which also supplies the representative consonants of Caledonia. The great forest of the Central Highlands would be very naturally spoken of as the Woods, Coiltean; Caledonii being only a Latin derivative.

With the spread of Christianity the Caledonians became the great people in Albin. In the later ages they consisted of Gaelicised Albinians, Gaels, and Brythonised Gaels. Among them appeared those who stand first on the roll of literary Scots: the poetry and tales of the Féinne developed into their present shape in the hands of the ancient Christian Gaels of our land. The poetic compositions which relate to this period furnish us with gleams of life from the borderland of decadent heathenism and Christianity.

From the first proclamation of the latter onwards the outlines of Scottish story become continually clearer, shining more and more until the day of national freedom and independence shone on a brave and struggling people. In glancing very briefly at the history of the Gael of Albin we find that it naturally suggests the following periods, described by terms which indicate the fresh elements introduced on fresh changes taking place:—

I. The Pre-Celtic Period embraces the unrecorded ages which partially terminated in the third century, when the influence of Christianity began to be felt. The Roman province in Scotland became nominally Christian by the Imperial adoption of Christianity by Constantine in the year 313.

II. The Celtic Period extends from the third century to the year 1068. During these dark and unsettled times there was much intercourse carried on between the old inhabitants of Albin and the people of Lochlin; generally the intercourse took the form of a fierce struggle for supremacy. In 1068 Malcolm III. married an English princess, known afterwards as the saintly Queen Margaret; Gaelic afterwards ceased to be the language of the Scottish Court. At that time Picts and Scots being united under one monarchy the sway of the Northmen in the north-west became much enfeebled. The power of the latter was completely broken by the disastrous defeat of Haco, at Large, in 1263.

III. The Norman or Feudal Period extends from 1068 to 1567. Few of the Gaelic preachers, or representatives of the early Scottish Church, survived the repressing influence of Queen Margaret, who was a zealous Roman Catholic. The Norman conquest of England caused many Saxons to seek refuge in Scotland, where they were welcomed by the Queen and her royal husband, Ceann-Mor. Norman influences also began to be felt in Scotland. The lands of Celtic chiefs were chartered away by the King to Norman barons, of whom many became as Celtic and as identified with the Gaelic inhabitants as the Celtic mormaers whom they supplanted. The patriarchal system began to decay, and feudalism was gradually introduced.

IV. The Protestant and Jacobite Period extends from the middle of the sixteenth century to the year 1745, when Jacobitism on Culloden Moor received its death-blow. The nominal first, afterwards the actual, acceptance of the Reformation doctrines by the Scottish Celts in the sixteenth century has very vitally affected their literature, as well as completely changed their relations with the Irish Celts.

V. The Anglo-Gaelic Period begins in 1745. The influence of the English language and English thought has been extending in the Highlands since then; while through the general intermingling of races, and a better mutual understanding, the prejudices of Celt and Saxon respectively have been everywhere dying away, especially among the classes by whom the force of the democratic tendencies of our age has been felt and acknowledged.

The dates assigned to the above periods are only approximately accurate, but they may serve to shadow forth some of the chief influences which have been at work in the history of Celtic Scotland, and of which we have traces in the literary annals of the Gael. Perhaps the surprising thing in connection with these meagre annals is the fact that there are any literary remains at all, when it is remembered how frequent and how violent have been the changes which have occurred in the course of the history of Albin.
