579. CONCERNING ANGELIC CHOIRS For several days many angelic choirs have been heard around me which I cannot well distinguish, except the Mahomedan choirs; for they vary their gyrations, which I could observe. There are those who continue the gyre without a note of any intervening stop. There are those which continue and terminate in two intervals, so that there were heard, as it were, three-fold, four-fold, five-fold interpunctions of the gyrations. There are those who accomplish six, as it were, sensible intervals in each circumgyration, which is so swift that one circumgyration is accomplished in scarcely one short second. 1748, Jan. 27.
