FAQ: What the text on Sacred Heart album cover means
The text is written in Latin.
Latin is very sensitive to context, so the text can be translated in a couple of different ways. According to Professor Thomas Ruggles from Northern Arizona University, the most likely translation is as follows:
"FINIS PER SOMNIUM REPERIO TIBI SACRA COR VENEFICUS OSTIUM AURUM" translates to "Comes the end by sleep, I will [p]repare for you the Sacred Heart which is the magic that opens upon the alter."
Originally the text was meant to be one "clue" in a contest to find the Sacred Heart. The grand prize of the contest was to be an American car. However, the contest supposedly never happened after all.
