After the educational reforms of the 1970s and 80s (including the banning of school prayer), deities like Jupiter no longer presided over institutions.

It's been said that "the concept of a single God is sophomoric," and here's proof.  From Lebanon Valley's 1910 yearbook.

From Swarthmore's 1988 yearbook.

Reblog if Jesus is your faculty.  From Montreat-Anderson's 1974 yearbook.

An X for a halo?  Presumably it's the tail end of the ichthys symbol ("sign of the fish") of Christianity, but we've never before encountered it this way (we have gaps!)  The red "64" sticker seems like a sun that Jesus is warding off.  The sun and the Son.  In mathematics, 64 is known as a "centered triangular number" (symbolic here of the Holy Trinity?)  Of course, there are 64 demons in the Dictionnaire Infernal, and 64 hexagrams in the I Ching, and 64 squares on a chess board, so there are many (unsatisfactory) ways to interpret the cover of Sacred Heart's 1964 yearbook.

From The Mayans, 1938.
