http://www.clanarans.com/ca/catalog/ Granted this site is also SELLING sweaters, it has a great history on the origins of aran sweaters, I didn't know that it was that involved... The Aran Sweater takes its name from the set of islands where it originated many generations ago, off the West coast of Ireland. The Aran Islands lie at the mouth of Galway Bay, at the mercy of the relentless Atlantic Sea. The Islanders were fishermen and farmers whose lives and livelihoods were deeply intertwined. The Aran Sweater was born of this environment, passed down from generation to generation, and has since become the ultimate symbol of Irish Clan heritage. History From its origins, the sweater has been intimately linked to clans and their identities. The many combinations of stitches seen on the garment are not incidental, far from it. They can impart vast amounts of information to those who know how to interpret them. The sweaters were, and remain, a reflection of the lives of the knitters, and their families. On the islands, patterns were zealously guarded, kept within the same clan throughout generations. They were often used to help identify bodies of fishermen washed up on the beach following an accident at sea. An official register of these historic patterns has been compiled, and can be seen in the Aran Sweater Museum on the Aran Islands.
