I would like to know the meaning of the symbols on a Byzantine Cross that I saw.  Each end of the cross had a letter symbol on it.  
 
a "P" on the left
 
a "A" on the top
 
a "X" on the Bottom
 
It also had a dove in the middle with a vine-like design hanging underneath it. I couldnt make out the symbol on the bottom, but I attached this link to show you what Im talking about.

Can anyone tell me the meaning of these symbols?
 
Peace and Blessings,
