The existing half-ruinous cell answers, I would first venture to remark--and answers most fitly and perfectly--to the two characteristic appellations used respectively in the _Scotichronicon_ and in the _Historiae Scotorum_, to designate the cell or oratory of the Inchcolm anchorite at the time of King Alexander's three days' sojourn on the island. These two appellations we have already found in the preceding quotations to be _capellula_ and _sacellum_. As applied to the small, rude, vaulted edifice to which I have endeavoured to draw the attention of the Society, both terms are strikingly significant. The word used by Fordun or Bower in the _Scotichronicon_ to designate the oratory of the Inchcolm anchorite, namely "capellula," or little chapel, is very descriptive of a diminutive church or oratory, but at the same time very rare. Du Cange, in his learned glossary, only adduces one example of its employment. It occurs in the testament of Guido, Bishop of Auxerre, in the thirteenth century (1270), who directs that "oratorium seu _capellulam_ super sepulchrum dicti Robini construent." This passage further proves the similar signification of the two names of oratorium and capellula. The other appellation "sacellum," applied by Boece to the hermit's chapel, is a better known and more classical word than the capellula of the _Scotichronicon_. It is, as is well known, a diminutive from sacer, as tenellus is from tener, macellus from macer, etc.; and Cicero himself has left us a complete definition of the word, for he has described "sacellum" as "locus parvus deo sacratus cum ara."[64]
