An example of the rosy cross symbol predating the early Rosicrucian manifestos is that shown on the central panel of the Harbaville Triptych, which is Byzantine and comes from the 10th or 11th century. The symbol is a Calvary cross with a rose in its centre, which is identical with what the masonic/rosicrucian scholar Manly Palmer Hall claimed to be the original symbol of the rosicrucians.
