During those years, everything attracted Peter’s curiosity. He asked for a dining-room clock, a statue of Christ, a Kalmuck saddle, a large globe, a performing monkey. He wanted to know how things worked, he loved the sight and the feel of tools in his large hands; he watched craftsmen use these tools, then he copied them and savored the sensation of biting into wood, chipping stone or molding iron. At the age of twelve, he ordered a carpenter’s bench and mastered the use of axes, chisels, hammers and nails. He became a stonemason. He learned the delicate business of turning a lathe and became an excellent turner in wood and later in ivory. He learned how type was set and books were bound. He loved the clang of hammers on glowing red iron in the blacksmith’s shop.
