embroidery completes a legend. The books became unintelligible,
so the story continues, the moment Longarad
died. At the same instant the satchels in all the Irish
schools and in Columba's cell slipped off their hooks on to

A quarrel about a book, we are told, changed his
career. He borrowed a Psalter from Finnian of Moville,
and made a copy of it, working secretly at night. Finnian
heard of the piracy, and, as owner of the original, claimed
the copy. Columba refused to let him have it. Then
Diarmid, King of Meath, was asked to arbitrate. Arguing
that as every calf belonged to its cow, so every copy of a
book belonged to the owner of the original, he decided in
Finnian's favour. Columba thought the award unjust, and
said so. A little later, after another dispute with Diarmid
on a question of monastic immunity, he called together his
tribesmen and partisans, and offered battle. Diarmid was
defeated. For some reason, not quite clear, these quarrels led
to Columba's voluntary exile(c. 563). He sailed from Ireland,
and landed upon the silver strand of Iona, and to the end of
his days his work lay almost entirely amid the heather-covered
uplands and plains of this little island home.[1] Iona became
a renowned centre of missionary work, quite overshadowing
in importance the earlier "Scottish" settlement
