Answer:
Well slightly you could say that it being called "allegorical" would go with the theme, the theme may be jealousy which could be the reason Venus gave all the nearly impossible (and inevitable) tasks to do, although Venus was possibly jealous because of Cupid liking Psyche and Psyche being mortal.
The statement fits with the theme of the story, because it wasn't made clear or stated that Venus was jealous, it used her actions to foreshadow (is that the right word for it?) the theme. Similar to how Psyche means soul and butterfly and how her soul is made immortal, like a transition for a caterpillar to a butterfly.
