Magic wheel, draw that man to my house. Among the Arcadians there is a plant, hippomanes, that makes all the fillies and swift mares run mad over the mountains. So may I see Delphis come out of the gleaming wrestling school and cross into this house like a man gone mad.

ἱππομανές means "horse-madness." Simaetha names it as a plant of Arcadia that sends fillies and mares raving over the mountains. LSJ identifies the plant at this very line as thorn-apple, Datura stramonium, "of which horses are madly fond, or which makes them mad," and records a second hippomanes: a small black growth on the forehead of a newborn foal, "held to be a powerful φίλτρον," a love charm (Aristotle, History of Animals 577a). Cholmeley notes that it is not clear whether she uses the plant here or only names its power. The wish is plain. The wrestling school is "oiled" because young men rubbed themselves with olive oil to train, and she wants Delphis to come out of it as mad for her as a mare in season.
