petal [petl], scene [si:n], holocaust [ˈhɔləkɔ:st]

In the middle of the ceiling hung a cluster of gold buds; these had opened like the petals of a great carven rose, and from them billowed a gray mist that swiftly filled the chamber. Instantly the scene changed from one of hysteria to one of madness and horror. The trapped men began to stagger; they ran in drunken circles. Froth dripped from their lips, which twisted as in awful laughter. Raging, they fell upon one another with daggers and teeth, slashing, tearing, slaying in a holocaust of madness. Murilo turned sick as he watched and was glad that he could not hear the screams and howls with which that doomed chamber must be ringing. Like pictures thrown on a screen, it was silent.

Outside the chamber of horror Thak was leaping up and down in brutish glee (вне комнаты ужаса Так скакал вверх и вниз = подпрыгивал в зверском ликовании), tossing his long hairy arms on high (вскидывая вверх свои длинные волосатые руки; to toss — бросать; вскидывать;on high — наверху). At Murilo's shoulder Nabonidus was laughing like a fiend (у плеча Мурило Набонидус хохотал, как одержимый; fiend — дьявол; одержимый человек).

"Ah, a good stroke, Petreus (о, хороший удар, Петреус)! That fairly disemboweled him (он мило распотрошил его)! Now one for you, my patriotic friend (теперь один тебе, мой патриотичный друг)! So (вот так)! They are all down (они все лежат: «внизу»), and the living tear the flesh of the dead with their slavering teeth (и живые рвут плоть мертвых слюнявыми зубами = зубами, пуская слюни; to slaver — пускать слюни)."
