232 THE BOY CRUSADERS. the bath, and with food, were invited by the grand vizier to repair to the presence of the caliph. It was not, however, without much ceremony, and some mystery, that the Templar and the English knight were admitted into the interior of a palace within whose precincts no Christian, save as a cap- tive, had ever before set foot. First, they were euided through dark passages, guarded by armed Ethiopians, and then into open courts so richly and beautifully adorned, that they could not refrain from expressing their admiration. ‘Certes,’ exclaimed Bisset, halting, ‘the caliph must, of all princes, be the richest; and I should not much marvel to hear that he had discovered the philosopher’s stone, which turns everything into gold, and of which my countryman, Roger Bacon, is said to be in search. Nevertheless, he does not seem to have studied the Roman poet, who tells us that treasure is hardly worth having, unless it is properly used.’ ‘In truth, sir knight,’ said the Templar, ‘the farther we go, the greater is the splendour and state.’ At length the ambassadors reached a magnificent chamber, where the caliph awaited them. At first, however, he was concealed from them by a curtain wrought with pearls. But the grand vizier thrice prostrated himself to the ground; and, as he did so, the traverse was drawn aside, and the caliph appeared arrayed in gorgeous robes, seated on a throne of gold, and surrounded by his eunuchs, who seemed both surprised and grieved to see Christians in that place and presence.
