Knox's personal aspect did not give signs of the uncommon strength which his unceasing labours demanded, but, like many men of energy, he had a perpetual youth of character and vigour. After his death, Peter Young described him as he appeared in his later years. He was somewhat below the "just" standard of height; his limbs were well and elegantly shaped; his shoulders broad, his fingers rather long, his head small, his hair black, his face somewhat swarthy, and not unpleasant to behold. There was a certain geniality in a countenance serious and stern, with a natural dignity and air of command; his eyebrows, when he was in anger, were expressive. His forehead was rather narrow, depressed above the eyebrows; his cheeks were full and ruddy, so that the eyes seemed to retreat into their hollows: they were dark grey, keen, and lively. The face was long, the nose also; the mouth was large, the upper lip being the thicker. The beard was long, rather thick and black, with a few grey hairs in his later years. {12} The nearest approach to an authentic portrait of Knox is a woodcut, engraved after a sketch from memory by Peter Young, and after another sketch of the same kind by an artist in Edinburgh. Compared with the peevish face of Calvin, also in Beza's Icones, Knox looks a broad-minded and genial character. Despite the uncommon length to which Knox carried the contemporary approval of persecution, then almost universal, except among the Anabaptists (and any party out of power), he was not personally rancorous where religion was not concerned. But concerned it usually was! He was the subject of many anonymous pasquils and libels, we know, but he entirely disregarded them. If he hated any mortal personally, and beyond what true religion demands of a Christian, that mortal was the mother of Mary Stuart, an amiable lady in an impossible position. Of jealousy towards his brethren there is not a trace in Knox, and he told Queen Mary that he could ill bear to correct his own boys, though the age was as cruel to schoolboys as that of St. Augustine.
