4448. CONCERNING THE HELL OF THE NEPHILIM OF THIS TIME, PROPERLY OF THE SIRENS. Certain sirens were with me for a whole year, who had at their command a most filthy and profane subject. They who have been such in this life as to become sirens hereafter, are every where spoken of or described in the world as most estimable, as to all kinds of external decorum, and [polished] manners, and what are termed intellectual endowments. Preeminent in this class are the sirens who properly rank among the Nephilim [giants], having most filthy interiors, being given to magic and adulteries beyond all others. They esteem as nothing the most impious and abominable adulteries, laboring continually to destroy not only the conscience, but the body also, and even burning to bring down the soul to the lowest hell. In a word their profane hell itself was concentrated in their subject; so also in others of this kind.
