"Her face was sickly pale, her whole body lean and wasted, and she squinted horribly; her teeth were discoloured and decayed, her poisonous breast of a greenish hue, and her tongue dripped venom. … Gnawing at other, and being gnawed, she was herself her own torment."
Invidia is an ancient Roman Goddess of Envy wo personified jealousy and hatred. Invidia according to Roman mythology, is pitied by the Roman deities who sees her as spmewhat hideous and spiteful. She holds a great grudge against her kind and seeks to poison all creation with her taint of hate, one soul at a time.
Invidia is a personification of envy, often envisioned as a woman, though it can also simply be used as a term for the emotion (without the personification aspect): in medieval times Invidia was considered one of the Seven Deadly Sins and was drawn as a woman with a serpent coiled round her breast and biting her heart, "to signify her self-devouring bitterness; she also raises one hand to her mouth to show she cares only for herself"
