Agostino Ramelli and ‘The Book Wheel’
By Ken Zurski
Agostino Ramelli was a military engineer, which meant he wore the armored suit and carried the sword, but used his brain rather than brawn on the battlefield. This came in handy during the 16th century French Wars of Religion. The Italian born Ramelli went to France, took up arms with the Catholic League, and was captured by the Protestants (Huguenots). While incarcerated, Ramelli not only found a way to break out, but in as well.
After he escaped – or was exchanged – Ramelli returned and breached the fortification by mining under a bastion. From that point on, he called himself “Capitano” and dedicated his life to figuring things out.
In 1588, he released a book titled, Various and Ingenious Machines of Capitano Ramelli. The expertly illustrated book was a compilation of 195 machines that made laborious tasks more practical. Many of the machines lifted things in crafty ways, like water, or solid objects, like doors off their hinges. One machine milled flour using rollers rather than stones.
Then there was the Book Wheel.
“This is a beautiful and ingenious machine, very useful and convenient,” Ramelli wrote. By convenient, he meant for those suffering from gout, a painful joint disease which made walking or standing difficult. A noble gesture, for sure, but the wheel itself was six-feet in diameter. So its doubtful Ramelli designed it strictly for the disabled. Nevertheless, its usefulness is left up to the user to decide. The operator remains seated while the books, eight in all, each come to the front by turning the wheel.
Ramelli was especially proud of the gearing system that kept the books constantly level to the ground. He built an intricate gear for each slot and prominently featured a diagram in his book. The impressive technology was similar to that used in an astronomical clock.
It was also wholly unnecessary.
A simple swivel pivot and gravity could do the trick just as engineer George Ferris would prove many centuries later in a similar design of a wheel carried people rather than books.
Speculation is Ramelli knew this, but as a mathematician, and a bit of a swank, couldn’t help himself.
