A schoolboy was so perfectly beautiful and sweet-voiced that the teacher, in accordance with human nature, conceived such an affection towards him that? he often recited the following verses:

 I am not so little occupied with thee, O heavenly face, 
 That remembrance of myself occurs to my mind. 
 From thy sight I am unable to withdraw my eyes 
 Although when I am opposite I may see that an arrow comes. 

Once the boy said to him: `As thou strivest to direct my studies, direct also my behaviour. If thou perceivest anything reprovable in my conduct, although it may seem approvable to me, inform me thereof that I may endeavour to change it.? He replied: `O boy, make that request to someone else because the eyes with which I look upon thee behold nothing but virtues.?

 The ill-wishing eye, be it torn out 
 Sees only defects in his virtue. 
 But if thou possessest one virtue and seventy faults 
 A friend sees nothing except that virtue.
