Lugones' "The Horses of Abdera"

An interesting story which reads like something of a parable. The city of Abdera prides itself on its horses and spoils them until they rebel, besieging the city that has spoiled them. As with "The Firestorm" there's something creepy about the scenes of urban destruction, this time by a somewhat fantastic variation on the violence of mobs. It ends with a deus ex machina (emphasis on the deus) that had me scratching my head, making it a little less satisfying then Firestorm. It was hard to tell what the horses were meant to represent. Spoiled youths? Immigrants? The working class? (My guess would be the latter, though I'd have to know more about Lugones' politics to say definitively.)
