The other item that catches Westerners with zero is
their number five is the circle.
It possible the medieval Spaniard academics choose
the circle because it was the farthest ordinal sequence
they could get from the Arabic dot in both directions
(on a line?) Then they could "borrow" the concept from
the hated Moors, but at the same time not admit they
used the same symbol? Or at least think they were as
opposite in belief from the Moors as they could get?
That is a just a weird hypothesis of mine. As the
religious animosity of the period could conceive of no
bounds of twisting the concepts of outsider thought.
And did the adoption of Arabic numerals require church
approval at some point? I seem to recall the church
holding on to Roman numbers longer than say, German
bankers or Venetian traders.
