In Medieval lore they believed Panthers were beautiful, multicoloured cats with a sweet odored breath that would drew in its prey then slept for 3 days.

This lead them to use the Panther as a representation of Jesus Christ, who drew all mankind to him.
A dragon represented the devil, who feared Christ and hid from him.
The many colours of the panther symbolizes the many qualities of Christ.
After Christ was sated with the mockery and abuse of the Jews, he fell asleep in death and entered the tomb. Descending into hell he bound the dragon.
After three days Christ left the tomb and roared out his triumph over death.
The sweet breath of the panther that drew all animals to it is a symbol of the words of Christ that draw all to him, Jews and Gentiles alike.

Have a good Friday everyone!
