It's the Pax Christi symbol, said the have been composed/seen by Emperor Constantine (a merging of the Greek letters chi and rho):
According to Sir Flinders Petrie - the Egyptologist - the monogram Chi-Rho was the emblem of the Egyptian God, Horus, thousands of years before Christ and is therefore a link between Horus the savior, and Christ the savior. I had already noted on several occasions the links between these ancient characters and so this was highly believable and conclusive.
And also notice the alpha and omega signs.. the beginning and end... of the Yule wheel??
Another 'christian' influence in the OLB??
From the OLB:
"What appears at the top is the signs of the Juul—that is, the first symbol of Wr-alda, also of the origin or beginning from which Time is derived; this is the Kroder, which must always go round with the Juul."
Well, what is that 'kroder' thing... it is a wheelbarrow : http://kroder-krooder.hyves.nl/ (or the one using it, a "kruier"/"krooier" in Dutch)
Now look again at the chi-rho symbol again, and look at the top.
Nice 'kroder', eh??
