@wis75 - According to uwalumni.com’s Ask Abe:
"The phrase “Numen Lumen,” developed as part of the University of Wisconsin-Madison’s seal and motto, is Latin and can be translated to mean, “God, our light.” But, according to a University Communications News Library article, the UW’s first chancellor, John Lathrop, who assisted in the creation of the motto, interpreted it to mean, “The divine within the universe, however manifested, is my light.”
On Wisconsin!
