The name
Ailbe was explained in the
Vita Albei as a derivative of
ail 'a rock' and
beo, 'living'. In the words of Baring Gould and Fisher this is "a very doubtful etymology". It is clearly related to the story of his being exposed behind a rock after his birth, before being cared for by a wolf (
Vita Albei 2) and looks very much like
folk etymology. Nevertheless, we can note a sporadic association of Ailbe (as a saint or mythological figure) with ' rocks' (Irish
ail). The
Lia Ailbe (stone of Ailbe) on the
Magh Ailbe (plain of Ailbe) may be in origin tautological, while a
Sliabh Ailbe was associated with a legendary figure
Ailbe in
Duanaire Finn. The
Inbher Ailbhine mentioned in Tirechan's
Vita Patricii (
Tirechan 5.2) may contain
ail, 'a rock', according to Watson. It is at a "marvellous stone altar ( = prominent rock with religious associations ) on the mountain of the
Ui Ailello" where Patrick was said to have installed the second St Ailbe (of
Sencua) - probably at the old site of the church of Shancoe, County Sligo, where a large rock overlooks a well:. This might all be best explained by a typical process of sound assimilation of
ail 'a rock' to the name
ail-be. The root
albho- 'white, bright' as in Latin
albus, 'white' appears to figure in the names of various deities or semi-deities, or names with likely mythological associations, hence the
Mons Albanus.
Albula as an old name for the Tiber and the legendary
Alba Longa in Latium; the Germanic deities
Albiahenae the semi-divine prophetess,
Albruna mentioned by Tacitus (Vulgar Latin
Aurinia:
Germania 8) or the spiritual or demonic beings from the Germanic world, which are represented in modern English by the word, 'elf'; the
Alphito which was recorded as the name of an 'ogress' or 'nursery bugbear' and might well have been appropriate to an earlier strata of Greek gods; and possibly the ‘
R̥bhus’ of Indian mythology and the Rhig Veda. This root may also be found in the names of Celtic deities such as
Albarinus,
Albocelo (if they do not contain Latin
Albus) and possibly the deity
Albius recorded in a single inscription from Aignay-le Duc,. However the root
albho- 'white, bright' does not figure in Irish or in fact in any of the extant Celtic languages. It may figure in the Celtic language of ancient Gaul (as in the names above) but there it may, in fact, have been borrowed from the ancient Ligurian language (the root is very common in place names from ancient Liguria). There does, however, appear the root
albi(i̭)o-, 'world' in the Brittonic Celtic languages: as seen for instance in Wesh
elfydd, 'world, land'. In fact, this root has convincingly been argued to be related to the root
albho- 'white, bright' and it certainly appears in the Gaulish divine name
albio-rix ("king of the world", parallel to
Dumno-rix and
Bitu-rix of similar meaning) . However it does not appear in Irish, with one sole exception: the Irish name for 'Britain', that is the Irish version of the name
Albion found in ancient sources as the oldest recorded name for Britain. This appears in Irish as
Albe-,
Alpe- and
Albu,
Alpu. There is, however, no obvious explanation for this name to appear in the form
ailbe and the root
albi(i̭)o- would not take that form in Irish, according to the way that language normally developed. The
i, in the
ai of
Ailbe, is not a full vowel but represents an audible 'glide' before a palatalised
l. This palatalised
l, with
i-glide is not found in Irish
Albu, 'Britain'. All of this renders the precise form of the name
Ailbe, in Irish, arguably, somewhat mysterious. ==Legacy==
