And in his sleep a vision came to him saying, “Lancelot, rise up and take thine armour, and enter the first ship that thou shalt find.”

When he awoke he obeyed the vision, and rode till he came to the sea-shore, and found there a ship without sails or oars, and as soon as he was in it he smelt the sweetest savour he had ever known, and seemed filled with all things he could think of or desire.  And looking round he saw a fair bed, and thereon a gentlewoman lying dead, who was Sir Percival’s sister.  And as Sir Lancelot looked on her he spied the writing in her right hand, and, taking it, he read therein her story.  And more than a month thereafter he abode in that ship and was nourished by the grace of Heaven, as Israel was fed with manna in the desert.

And on a certain night he went ashore to pass the time, for he was somewhat weary, and, listening, he heard a horse come towards him, from which a knight alighted and went up into the ship; who, when he saw Sir Lancelot, said, “Fair sir, ye be right welcome to mine eyes, for I am thy son Galahad, and long time I have sought for thee.”  With that he kneeled and asked his blessing, and took off his helm and kissed him, and the great joy there was between them no tongue can tell.

Then for half a year they dwelt together in the ship, and served God night and day with all their powers, and went to many unknown islands, where none but wild beasts haunted, and there found many strange and perilous adventures.

And upon a time they came to the edge of a forest, before a cross of stone, and saw a knight armed all in white, leading a white horse.  Then the knight saluted them, and said to Galahad, “Ye have been long time enough with your father; now, therefore, leave him and ride this horse till ye achieve the Holy Quest.”

Then went Sir Galahad to his father and kissed him full courteously, and said, “Fair father, I know not when I shall see thee again.”

And as he took his horse a voice spake in their hearing, “Ye shall meet no more in this life.”

“Now, my son, Sir Galahad,” said Sir Lancelot, “since we must so part and see each other never more, I pray the High Father of Heaven to preserve both you and me.”

Then they bade farewell, and Sir Galahad entered the forest, and Sir Lancelot returned to the ship, and the wind rose and drove him more than a month through the sea, whereby he slept but little, yet ever prayed that he might see the Sangreal.

So it befell upon a certain midnight, the moon shining clear, he came before a fair and rich castle, whereof the postern gate was open towards the sea, having no keeper save two lions in the entry.

Anon Sir Lancelot heard a voice:  “Leave now thy ship and go within the castle, and thou shalt see a part of thy desire.”

Then he armed and went towards the gate, and coming to the lions he drew out his sword, but suddenly a dwarf rushed out and smote him on the arm, so that he dropt his sword, and heard again the voice, “Oh, man of evil faith, and poor belief, wherefore trustest thou thine arms above thy Maker?” Then he put up his sword and signed the cross upon his forehead, and so passed by the lions without hurt.
