The elucubrations of the lute, pulsing from the finger strums of starlight, Plum-twilight of the Colosseum like an emperor’s bowl of plucked fruit, As the night’s ghost-gods are tuned to Castel Sant’Angelo, Hadrian’s tomb, Who drink the dwindling hours from the wine-stemmed glass of musical moon.
But come the times out of tune, the dwindling of stone is the going blind of Rome: Rome is built upon millions of eyes closed with the underside of their lids tattooed, By labyrinthine aqueducts, far-aging roads, and traceries of Nero’s Golden Home. Then death its sight-sun blooms through; death the architect of Seven Hills renews.
Elucubrations here means night compositions or writing/composing at night.
The Ancient Romans believed in the “Di Manes” or “Manes,” the collective soul of the dead. Tombs were often inscribed with “D.M.” to acknowledge the spirits of the dead or the “ghost-gods.”
