He knew the cause of every malady
Were it of cold, or hot, or moist, or dry,
And where engendered and of what humour.
He was a very perfect practisour.
His library was a wonderful one considering the rarity of books at that time.
Well knew he the olde Esculapius
And Dioscorides, and eek Rufus
Old Ypocras, Haly, and Galien,
Serapyon, Razis, and Avicen,
Averrois, Damascien, and Constantyn,
