" Zephyr also has, with his sweet breath,..."See in text(The General Prologue - The General Prologue)
Zephyr is the Greco-Roman god for the west wind, one of four directional wind gods in Greco-Roman mythology. He is generally winged, handsome, and young in artistic depictions. The god is generally portrayed as the personification of spring, holding or associated with unripe fruit. “Sweet breath” here refers to a wind commanded by Zephyr. By characterizing this breath as “sweet,” Chaucer creates an implicit connection between Zephyr blowing and spring approaching.
