BULLSHIT. This is part of the later Arthurian legend which has
absolutely no historical basis at all.
"Blaise" was St. Blaise, whose feast day of 1st/2nd February (Roman
CANDLEMAS/Celtic IMBOLC) was shared with Bride/Bridget, an ancient
Celtic goddess of fire, poetry, inspiration, brewing, healing, and
smithcraft (also with dairy work, since with the latter three topics
all used a cauldron heated over a fire). St. Blaise originated as a
Gaulish wolf-god known as "Blazey" (CF: book THE BLACK VIRGIN). Blaise
was also associated with wool-combing, and sheperds were especially
vigilant about watching for wolves attacking their flocks.
Blaise was one of the patron saints of the city of York, and was
featured in processions and festivals in that town in medieval times,
due to the heavy concentration of sheep-raising, wool processing, and
weaving in Yorkshire/Northumbria.
Please note that in the early poems of Myrddin aka Merlin Caledonius,
he is given a companion of a pig, and that Merlyn was also associated
with wolves and stags.
This entire tradition is a bleed-over from early British pagan
religious tradition. It has no basis in historical fact, apart from
the one known fact that a northern British king, Gwendolleu ap Ceidio
(king of Selgovia, the tribal lands of the Selgovae) employed his
second cousin from the royal lineage of Yorkshire/Ebrauc (Myrddin) as a
bard/sorceror -- Gwendolleu was killed in battle at his fort of Caer
Gwendolleu (also called: Caerwinley OR Arfderydd/Arthuret) ca. 568 CE,
and Myrddin/Merlyn supposedly survived and became a fugitive in the
northern mountains for years after the battle. I say "supposedly"
because, according to the ancient genealogy of the Coeling royal
lineages (CF: earlybritishkings.com), the man Myrddin Wyllt ap ap
Morfryn ap Morydd was born ca. 488 CE -- thus making him 80 yrs of age
in 568 CE. He could not possibly have survived another 30-50 years in
the northern wilderness, as the poems attributed to him claim.
The "MERLIN" of Arthurian legend, by the way, is a composite character,
comprised of:
1 -- the "Ambrosius" child mentioned in Nennius who prophesied for
Vortigern regarding the buried dragons under his continually-falling
tower of refuge
2 -- the druidically-trained pagan priest/bard/sorceror who was the
advisor of Arthur's father and Arthur himself
3 -- Myrddin, pagan priest/sorceror to Gwendolleu ap Ceidio, king of
two kingdoms: Selgovia and Galloway
4 -- Lailoken, a madman of Strathclyde whose legend was fused with
those of the first two men by Geoffrey of Monmouth.
