help whenever he wished to return.
Instead of riding a charger, Lohengrin was conveyed in a swan-drawn
skiff to Brabant, where he found Elsa praying for a champion to defend
her against Frederick of Telramund's accusation of having slain her
little brother, who had mysteriously disappeared.

Lohengrin, having proved the falsity of the charge by defeating the
accuser in a judicial duel, married Elsa, warning her she must never
seek to discover his name or origin, under penalty of seeing him
depart as suddenly as he had arrived. The machinations of Frederick of
Telramund, and of his artful wife, finally drove Elsa to propound the
fatal question, and, as soon as Lohengrin has sorrowfully answered
it, the swan appeared and bore him away! But, as Lohengrin departed,
Elsa's brother reappeared to serve as her protector.[32]

This--mostly German--version of the Grail legend--has been used by
Wolfram von Eschenbach for a long and famous epic, and by Wagner for
his operas Parzival and Lohengrin. In the French and particularly in
the English versions of the Quest for the Holy Grail, or Sangreal,
Percival is with the other knights of Arthur's Round Table when they
take this vow. He seeks for it, perceives it through a veil, but never
entirely achieves the quest, since that privilege is reserved for the
peerless Galahad.

The versions of the Holy Grail Story of which Galahad is hero run

latter's nurse having, by means of enchantment, made her to appear as
Guinevere--whom Launcelot loved. Deserted by the accidental father of
her coming child, this Elaine--daughter of King Pelles--took refuge in
a nunnery, where she gave birth to Galahad, whom when dying she
entrusted to the nuns. Brought up by those holy women and strengthened
in early infancy by frequent glimpses of the Holy Grail,--whose light
was blinding to all but the perfectly pure,--Galahad reached manhood
as pure as when he was born. One day Sir Launcelot and Sir Bors were
summoned from Camelot to a small church near by, to act as sponsors
for a young candidate for knighthood, who was presented to them by
some nuns. Launcelot and Bors, having thus heard Galahad take his
vows, were not surprised to see him brought into their midst on a gala
day, by Merlin or by the spirit of Joseph, and to hear him warmly
welcomed by Arthur. Some versions claim that Galahad, led to the Siege
Perilous, found his name miraculo
