But these defects need not blind us to the fact that this hypothesis made the mathematical progress of Hooke, Borelli and Newton much more easy and certain.
Borelli (1608-1679) as its most notable name, entered in a way on the mechanical study of anatomy suggested by Descartes, but was probably much more dependent upon the positive researches of Galileo.
Borelli (De motu animalium, Rome, 1680), explained that birds are enabled to grasp the twig on which they rest whilst sleeping, without having to make any muscular exertion, because the weight of the body bends the knee and ankle-joints, over both of which pass the tendons of this compound muscle.
GIOVANNI ALFONSO BORELLI (1608-1679), Italian physiologist and physicist, was born at Naples on the 28th of January 1608.
Borelli (1608-1679), whose treatise De motu animalium, published in 1680, is regarded as marking an epoch in physiology.
The most important men in this school after Borelli were Nicolaus Stensen (Steno), (1638-1686), Giorgio Baglivi (1669-1707) and Lorenzo Bellini (1643-1704).
We thus see that, while the great anatomists, physicists and chemists - men of the type of Willis, Borelli and Boyle - were laying foundations which were later on built up into the fabric of scientific medicine, little good was done by the premature application of their half-understood principles to practice.
This was made by Giovanni Alfonso Borelli and Abraham Ecchellensis from the free version in Arabic made in 983 by Abu 'l-Fath of Ispahan and preserved in a Florence MS. But the best Arabic translation is that made as regards Books i.-iv.

Conjointly with Giovanni Borelli he wrote a Latin translation of the 5th, 6th and 7th books of the Conics of Apollonius of Perga (1661).
Borelli in 1670.
Borelli was of opinion that flight resulted from the application of an inclined plane, which beats the air, and which has a wedge b action.
Borelli does not state the amount of upward bending, but one of his followers, E.
Strauss-Diirckheim agrees with Borelli both as to the natural and the artificial wing.
Marey repeats Borelli and Diirckheim with very trifling modifications, so late as 1869.
He endeavoured to construct an artificial insect on the plan advocated by Borelli, Strauss-Diirckheim and Chabrier, but signally failed, his insect never having been able to lift more than a third of its own weight.
