In laying before our readers the substance of the contents of Part I., we shall take the liberty of inverting the author's order of arrangement, and commence by the analysis of the word. The name Célé-dé is composed of the two words _céle_ and _dé_. The word _célé_ is of frequent occurrence in the early Irish manuscripts, and is the usual gloss on the words _socius_, _maritus_, where they occur in the Wurtzburg copy of St. Paul's Epistles and the St. Gall Priscian. From this it passes into the pronominal sense of _alius_, _alter_, and the adverbial of _seorsum_. More rarely it has the sense of _servus_, and in O'Davoren's Glossary is explained by _gilla_ = "a servant"; and with this interpretation it is found in modern Irish and Gaelic dictionaries. The other component, _dé_, is the genitive of _Dia_, "God", and is found as a kind of religious intensitive in combination with certain monastic terms, as anchorita Dei, monialis Dei. Thus Célé-dé may mean "spouse of God", or "friend of God", or "servant of God". Dr. Reeves prefers the last-mentioned interpretation, for the following reasons. The devotion and self-denial peculiar to the monastic life procured for those who followed it the special designation of _servi Dei_, which in time acquired a technical application, so that _servus Dei_ and _monachus_ became convertible terms, _ancilla Dei_ signified a nun, and _servire Deo_ a monastic life. In this sense, as Dr. Reeves shows by numerous quotations, it runs through the works of the Latin fathers, the acts of councils, and the biographies of saints. The writings of St. Gregory the Great (called in Ireland Bel-oir, the golden-mouthed) recommended this meaning especially to Ireland, where that father was in the highest repute. "Familiarised, therefore, to the expression _servus Dei_, it is only reasonable to suppose that the Irish would adopt it in their discourse, and find a conventional equivalent for it in the language of their country. To this origin we may safely refer the creation of the Celtic compound _célé-Dé_, which in its employment possessed all the latitude of its model, and in the lapse of ages underwent all the modifications or limitations of meaning which the changes of time and circumstances or local usage produced in the class to whom the epithet was applied" (pag. 2). Of this there are many examples: thus--1, the Four Masters, in the Irish Annals of 1595, apply the term to the Dominican Friars of Sligo; 2, the Book of Fenagh uses it of St. John the Evangelist; 3, in the Book of Leinster and the Book of Lismore, St. Moling, Abbot and Bishop of Ferns (ob. 697), classes himself among the céle-n-Dé, and implies that his associates were the miserable, that is, the sick and lepers; 4, In Scotland, whither the term entered with the Scotic immigrants, we find in the middle of the thirteenth century certain ecclesiastics entitled _Keledei sive Canonici_. Hence Dr. Reeves is
