# Spinning-wheel [View the canonical artwork record]() ## Artwork - Artist: [UNKNOWN MASTER, German]() - Date: 1451-1500 - Technique: Drawing ## Commentary From the 12th century to the Industrial Revolution there was a steady improvement in mechanical techniques, but no radical breakthrough. This could not happen until new sources of power were discovered. As long as man had to rely on his own strength, on that of animals, opportunities for progress were limited. This drawing shows a powder-mill containing an ingenious set of gears worked by hand. ## Related artworks - [12 scenes from the Life of Christ]() - [A Bath-House]() - [A carpenter at work]() - [A Knight of the Rehlinger Family]() - [A Lady]() - [Adoration of the Magi]() - [Adoration of the Magi]() - [Adoration of the Magi]() - [Adoration of the Magi]() - [Adoration of the Shepherds]() - [Altarpiece of the Seven Joys of Mary]() - [Altarpiece of the Seven Joys of Mary]() ## Attribution [Web Gallery of Art]()
