Of all man’s instruments, the most wondrous, no doubt, is the book. The other instruments are extensions of his body.

But the book is something else altogether: the book is an extension of memory and imagination.

Time is the tiger that devours me, but I am that tiger.

A man sets out to draw the world. As the years go by, he peoples a space with images of provinces, kingdoms, mountains, bays, ships, islands, fishes, rooms, instruments, stars, horses, and individuals.
