After posting about Cheynell’s 1650 Trinity book, I looked again at the title page and realized he didn’t publish it as a book about The Divine Triunity, but about the Divine TriNunity. As far as I can tell, he meant to spell it that way. Later readers who wrote about his book sometimes got the name right, and sometimes unconsciously corrected it (as I did), to Trinity. I haven’t read Cheynell’s book (still resting from the title), but I wonder if he uses the unconventional “trinunity” term throughout. And if he coined it himself. And if he did it just to mess with my head.
