Behold, the Kindle of the 16th Century
In his own book, published in 1588 and modestly titled The Various and Ingenious Machines of Captain Agostino Ramelli, the designer outlined his vision for a wheel-o-books that would employ the logic of other types of wheel (water, Ferris, “Price is Right”, etc.) to rotate books clockwork-style before a stationary user. Ramelli planned to use epicyclic gearing – a system that had at that point been used only in astronomical clocks – to ensure that the shelves bearing the wheel’s books (more than a dozen of them) would remain at the same angle no matter the wheel’s position. The seated reader could then employ either hand or foot controls to move the desired book pretty much into her (or, much more likely, his) lap.
