It was from Ireland that the Scots came to Scotland, and when
they came they brought with them many tales. So it comes about
that in old Scottish and in old Irish manuscripts we find the
same stories.

Many of the manuscripts which are kept in Ireland have never been
translated out of the old Irish in which they were written, so
they are closed books to all but a few scholars, and we need not
talk about them. But of one of the great treasures of old Irish
literature we will talk. This is the Leabhar Na h-Uidhre, or
Book of the Dun Cow. It is called so because the stories in it
were first written down by St. Ciaran in a book made from the
skin of a favorite cow of a dun color. That book has long been
lost, and this copy of it was made in the eleventh century.

The name of this old book helps us to remember that long ago
there was no paper, and that books were written on vellum made
from calf-skin and upon parchment made from sheep-skin. It was
not until the twelfth century that paper began to be made in some
parts of Europe, and it was not until the fifteenth century that
paper books became common in England.

In the Book of the Dun Cow, and in another old book called the
Book of Leinster, there is written the great Irish legend called
the Tain Bo Chuailgne or the Cattle Raid of Cooley.

This is a very old tale of the time soon after the birth of
Christ. In the book we are told how this story had been written
down long, long ago in a book called the Great Book Written on
Skins. But a learned man carried away that book to the East.
