It was his father who had taught him everything, and he had learned a great deal. Loristan had the power of making all things interesting to fascination. To Marco it seemed that he knew everything in the world. They were not rich enough to buy many books, but Loristan knew the treasures of all great cities, the resources of the smallest towns. Together he and his boy walked through the endless galleries filled with the wonders of the world, the pictures before which through centuries an unbroken procession of almost worshiping eyes had passed uplifted. Because his father made the pictures seem the glowing, burning work of still-living men whom the centuries could not turn to dust, because he could tell the stories of their living and laboring to triumph, stories of what they felt and suffered and were, the boy became as familiar with the old masters--Italian, German, French, Dutch, English, Spanish--as he was with most of the countries they had lived in. They were not merely old masters to him, but men who were great, men who seemed to him to have wielded beautiful swords and held high, splendid lights. His father could not go often with him, but he always took him for the first time to the galleries, museums, libraries, and historical places which were richest in treasures of art, beauty, or story. Then, having seen them once through his eyes, Marco went again and again alone, and so grew intimate with the wonders of the world. He knew that he was gratifying a wish of his father's when he tried to train himself to observe all things and forget nothing. These palaces of marvels were his school-rooms, and his strange but rich education was the most interesting part of his life. In time, he knew exactly the places where the great Rembrandts, Vandykes, Rubens, Raphaels, Tintorettos, or Frans Hals hung; he knew whether this masterpiece or that was in Vienna, in Paris, in Venice, or Munich, or Rome. He knew stories of splendid crown jewels, of old armor, of ancient crafts, and of Roman relics dug up from beneath the foundations of old German cities. Any boy wandering to amuse himself through museums and palaces on "free days" could see what he saw, but boys living fuller and less lonely lives would have been less likely to concentrate their entire minds on what they looked at, and also less likely to store away facts with the determination to be able to recall at any moment the mental shelf on which they were laid. Having no playmates and nothing to play with, he began when he was a very little fellow to make a sort of game out of his rambles through picture-galleries, and the places which, whether they called themselves museums or not, were storehouses or relics of antiquity. There were always the blessed "free days," when he could climb any marble steps, and enter any great portal without paying an entrance fee. Once inside, there were plenty of plainly and poorly dressed people to be seen, but
