1 fragmentary epigraph, 1 anonymous relief fragment, and 2 gods

This is the story of a document and of many people. The document is a red stone in the vault of a small church in Sinsheim (Germany) that no one would look at really; to the expert eye of the epigraphist, however, even this apparently unimportant stone with a small cluster of scattered letters ("RIO / SION / L") is sufficient to raise intriguing questions and open up a window on the Ancient World.
