context:
There went forth the fiat, "Against all the gods of Egypt I will execute judgment!" Each blow insults and abases some amongst them. Serapis blushes till his Nile waters, erst so translucent, turn to a blood red: Ra, the sun-god, is compelled to smile on Israel and frown on Mizraim. The sacred frog and fly become objects of loathing. The bull-god, Apis, cannot protect himself nor his fellow-cattle from the murrain. Seb, the earth, is covered with vermin. Osiris and Isis are extinguished in the sky; and Netpe, the vault of heaven, is covered with a shameful darkness as with a garment of mourning. The whole obscene brood are "hurled headlong flaming from the ethereal sky, In hideous ruin and combustion down To bottomless perdition."
