Calatrava Cross

I had never heard of it before, but maybe you can figure out something from this:

I heard it is jelly filled but I may be wrong.

Cross of Calatrava

When the Knights of the Calatrava went into battle they carried a flag
with four reversed anchors connected at it`s center.It was known as
the calatrava cross.The cross was thought to protect all that went
into battle.Each anchor or "Triad" had a special power.Patek Phillepe
is the first person I know of to discover the Calatrava Cross and use
it`s symbol.It was placed on the finest time pieces ever made.The
Scrolls are a reference to the dead sea scrolls.The secret of the Four
Triads is supposed to be the secret to the meaning of life.The Zodiacs
whole basis comes from the Four Triads.
