"A beautiful and ingenious machine, which is very useful and convenient to every person who takes pleasure in study, especially those who are suffering from indisposition or are subject to gout: for with this sort of machine a man can see and read a great quantity of books, without moving his place: besides, it has this fine convenience, which is, of occupying a little space in the place where it is set, as any person of understanding can appreciate from the drawing."

Agostino Ramelli, Italian Engineer and Innovator, 1588
