One day while in the altar at Sts. Anargyroi Vasili said to me “have you seen the angel in the floor?”.  He pointed at a seemingly random pattern in the marble, roughly between the prothesis and the altar table, so not really visible from outside.  And there it was, clear as day – the outline of an angel.  How did it get there?  I will leave it up to you to form an opinion.  It may well just be random, but I am going with what Hunter wrote in Ripple: “that was not made by the hands of men”.  Below are photos Demetri took.  One is unadorned and the other is enhanced to help you make it out.
