It is believed that this presentation of a literature which held
unrivalled sway over the imaginations of our ancestors, for many
centuries, will not be without benefit to the reader, in addition
to the amusement it may afford. The tales, though not to be
trusted for their facts, are worthy of all credit as pictures of
manners; and it is beginning to be held that the manners and modes
of thinking of an age are a more important part of its history
than the conflicts of its peoples, generally leading to no result.
Besides this, the literature of romance is a treasure-house of
poetical material, to which modern poets frequently resort. The
Italian poets, Dante and Ariosto, the English, Spenser, Scott, and
Tennyson, and our own Longfellow and Lowell, are examples of this.

These legends are so connected with each other, so consistently
adapted to a group of characters strongly individualized in
Arthur, Launcelot, and their compeers, and so lighted up by the
fires of imagination and invention, that they seem as well adapted
to the poet's purpose as the legends of the Greek and Roman
mythology. And if every well-educated young person is expected to
know the story of the Golden Fleece, why is the quest of the
Sangreal less worthy of his acquaintance? Or if an allusion to the
shield of Achilles ought not to pass unapprehended, why should one
to Excalibar, the famous sword of Arthur?--

"Of Arthur, who, to upper light restored,
With that terrific sword,
Which yet he brandishes for future war,
Shall lift his country's fame above the polar star."
