Many allusions in old records show how highly the confection was esteemed by those who could afford to take it. According to Buckle ("Miscell. Works," Vol. II, p. 303) it is first mentioned in English literature by Foucher de Chartres (1124). He had come to know of it in the first crusade. A "Pixis argenti ad Tyriacum" is named in the Close Roll of King John, 1208; in the old romance of Sir Tristrem (about 1250) a man is slain by a dragon; and "His mouth opened thai And pelt treacle in that man"; the "triacle box du pere apelle une Hakette garniz d'or" is mentioned among the precious effects of Henry V; in the Paston letters written in the reign of Edward IV we find allusions to "treacle pottes of Geane (Genoa) as my potecarie swerytht on to me, and moerovyr that they were never undoo syns that they came from Geane."
In early English books treacle was a term used metaphorically for the divinest blessings. Nothing could better prove the high appreciation in which it was held. Piers Ploughman (about 1370) writes, "Treuthe telleth that love ys tryacle for synne"; Chaucer (1340-1400) has "Crist, which is to every harm triacle"; in Coverdale's Bible (1535) the sentence in Jeremiah viii, 22 is rendered "Is there no triacle in Gilead?"; Sir Thomas More (1573) writes of "laying up a store of cumfort in your hart as a triacle against the poyson of desperate dread"; and later Milton speaks of "the treacle of sound doctrine"; Jeremy Taylor says, "We kill the Viper and make treacle of him; that is, we not only escape from but get advantage by temptations."
