36 INTRODUCTION. 
ninus, or Magnus, a physician of Milan, having 
made some additions and alterations, put his own 
name to it, and it has since been attributed to him. 
There is a work of Arnaldus, De Conservandé 
Juventute, et Retardandd Senectute, and another 
de Regimine Castra Sequentium, of the same class™. 
Villa Nova’s commentary is succinct, clear, and 
to the purpose. It well explains the precepts a¢- 
cording to the system of physic then received, 
confirms them by the authorities of Aristotle, Hippo- 
crates, Galen, Avicenna, Rases, Averroes, and other 
eminent writers, who were the genuine sources from 
whence they were derived. From its first appear- 
ance this commentary always accompanied the text, 
and it was printed with it in the earliest editions 
The fame of Arnald was inseparably connected with 
that of the poem, which was even sometimes attri- 
buted to him. Though subsequent editions may 
have refined the language, and multiplied authorities 
and illustrations, the original work of Villa Nova 
2 des Hommes illustres, vol. xxxiv. p- 8.
