Here, Helena admits that she loves many of Demetrius's "base and vile" qualities. It seems that love has the capacity to blind us (figuratively speaking) to the truth. This idea comes up again when Titania literally falls in love with Bottom – a "base and vile" creature.

Oberon tells us that, when the magic love "juice" is sprinkled into someone's eyes, it causes the person to fall instantly in love with the first creature he or she sees. Shakespeare seems to have borrowed this concept from Book 14 of Ovid's Metamorphoses, where Circe uses a magic potion to transform men into beasts.

After Puck has "translated" Bottom's head into that of an ass, Bottom becomes the butt of Shakespeare's biggest joke about transformation. Clueless that he's been transformed, Bottom declares that his friends have run away from him in fear because they're trying to "make an ass" out of him (3.1.16). Shakespeare probably got the idea from Apuleius's Golden Ass, a hilarious and ancient story about a guy who's turned into a donkey. Bottom's conversion is also key to the play's theme of transformation, a concept Shakespeare borrowed from Ovid's Metamorphoses.
