Whilst the author has described an Open-Air Mithraeum using the Symbols on the Stones with the skyward view in the context of pursuing a Mithraic belief, logically the principle could be applied to the pursuit of Christianity. Those Stones with a Christian Cross (and any biblically related items) would have served to explain the Christian belief with the addition of the skyward view to heaven beyond. With the components of the Open-Air Mithraeum deriving from what was physically seen in a Mithraic Temple perhaps, conversely, the outdoor Christian place of worship was the precursor to the indoor church. For the time period being considered there is no archaeological evidence of buildings for worship.
However, not only did the carvers create and collectively use that Shared Space on the surface of Symbol Stones, they arguably caused another Shared Space to be established – Places for Worship.
