John Wilkins (1614-1672) was an Anglican clergyman, natural philosopher, and author, and was one of the founding members of the Royal Society. He was the Bishop of Chester from 1668 to his death. Wilkins is one of the few persons to have headed a college at both the University of Oxford and the University of Cambridge. He was a polymath. In the first twenty chapters of the Mechanicall Magick, traditional mechanical devices are discussed such as the balance, the lever, the wheel or pulley & the block and table, the wedge, and the screw. Wilkin's also gives an outlook on future technical research like flying, which he anticipated as certain if only sufficient exercise, research, and development would be directed to these topics. In Chapter VII, Wilkins discusses various methods on how a man could fly, namely by help of spirits and good or evil angels, by the help of fowls, by wings fastened immediately to the body or by a flying chariot. The most probably way, however, would be a flying chariot. "which may be so contrived as to carry a man within it." and be equipped with some sort of engine. An incredibly interesting work, even incomplete. Plates and illustrations present well and are intact in modern binding. A reading copy despite imperfections. N° de ref. del artículo RAREB1648HPQX
