Confessions of a Young Exile (1976)

“No one was allowed to leave the theatre during his recitals, however pressing the reason. We read of women in the audience giving birth, and of men being so bored with listening and applauding that they furtively dropped down from the wall at the rear, since the gates were kept barred, or shammed dead and were carried away for burial.”
Cantante eo ne necessaria quidem causa excedere theatro licitum est. Itaque et enixae quaedam in spectaculis dicuntur et multi taedio audendi laudandique clausis oppidorum portis aut furtim desiluisse de muro aut morte simulata funere elati.

Variant: "The Upholder of the Cycles which supports the whole of Life, is water. In every drop of water dwells the Godhead, whom we all serve; there also dwells Life, the Soul of the "First" substance - Water - whose boundaries and banks are the capillaries that guide it and in which it circulates. More energy is encapsulated in every drop of good spring water than an average-sized PowerStation is presently able to produce."
