John Gower, The complete works of John Gower…
“ False Semblant is allied with Hypocrisy, and Envy steers their boat. Therefore flee this vice and let thy semblant always be true. When Envy desires to deceive, it is False Semblant who is his messenger; and as the mirror shows what was never within it, so he shows in his countenance that which is not in his heart. Dost thou follow this vice, my son?Nay, father, for ought I know; but question me, I pray you.Tell me then, my son, if ever thou hast gained the confidence of any man in order to tell out his secrets and hinder him in his love. Dost thou practise such devices? ”
