dividual here referred to, and so obtain grounds for determin- 
ing the date of the manuscript a priori. On the other hand, 
if we are permitted to assume that it was written A. D. 807, 
good reasons for this conclusion having been already shewn, 
we are enabled to account in a satisfactory manner for the 
appearance of the name in question. 
In the twenty-fourth chapter of Sir James Ware’s Anti- 
quitates Hibernice, where he gives an account of the acts of 
the Ostmen in Ireland, we find the following passage : 
** Anno 807, Dani et Norwegi in Hiberniam appulerunt, 
et Roscomaniam, regionemque adjacentem ferro flammaque 
vastarunt. Eodem tempore Cellacus Abbas cznobii S. Co- 
lumbe Huensis, multis e suis, Norwegorum crudelitate, inter- 
fectis, in Hiberniam profugit, et Kenanuse, alias Kenlisez in 
Midia, monasterium inhonorem S. Columbe sive condidit, sive 
restauravit. Cum vero annos circiter septem ibi prefuisset 
Abbas, Dermitio quodam in dicto czenobio Abbate relicto, in 
Ionam sive insulam Huensem reversus est, ubi, post annum 
unum vel alterum mortem obiit.” 
Ware does not indicate the sources from whence he has 
derived this account. It is confirmed, however, as regards 
the date and the history of Cellach, by the Manuscript An- 
nals in the Library of Trinity College, H.1,7, commonly called 
the Annals of Innisfallen; and mention is made in the Annals 
of Ulster, ad. ann. 806 (A. D. 807), of the building of the 
‘monastery at Kells. 
To the history of this Abbot of Iona it is by no means 
improbable that allusion may have been intended by the scribe 
who wrote the name of Cellach in the margin: and perhaps he 
may have thought that our Lord’s descriptive prediction of 
the miseries attending the destruction of Jerusalem ( Mark xiii. 
14-23) was not inapplicable to the sad visitation which had re- 
cently fallen upon Iona. 
With respect to the practice of writing Latin in Greek 
characters, of which so many instances occur in the Book of
