Constantine looked in the right direction, alone?
Constantine was the only one to see the 'phenomena/apparition'.
And he had thousands of legionnaires present. That according to
historic texts.
He must have been looking in the right direction, and such a meteor
would have taken on the appearance of an ancient Egyptian Ankh
that's how Emperor Constantine described its appearance.
[The Ankh does have some resemblance to the ancient Roman instrument of torture/execution and now of institutionalized Christianity, but the Ankh has also historically morphed into an astrological sign for Venus, feminism, etc.]
