This funerary sculpture of the Virgin Mary can be found in the Mount Carmel Cemetery in Hillside, Illinois. In addition to the symbolism of the Immaculate Heart of Mary, which the Virgin Mary points to, is also the image and symbolism of Mary standing on a snake. Look to the bottom of the statue.
In Genesis 3:15 God speaks to the serpent after the fall of Adam and Eve into sin, “I will put enmity between you and the woman, between your seed and her seed; He shall crush your head and you shall lie in wait for his heel.” In the Latin translation the passage read “she shall crush your head.”
The passage comes to be seen as a prophecy of the coming of the Messiah, Jesus Christ. Christ is the “seed of the woman.” Mother Mary is free from sin, both original and actual, and as such is viewed as the new Eve, the only woman who has a perfect enmity with the devil. It is the ultimate symbol of Mary’s victory over Satan.
In a larger sense it is viewed as the triumph of good over evil.
Gravely Speaking 
Very interesting! Thank you for sharing that about Genesis 3:15 for our God Jehovah God and His Son Jesus Christ has given us power over the Serpent. One day soon death will be destroyed and conquered and every tear shall be wiped from our eyes!
Continue to keep the good work continue to educate us about the grave/cemetery symbols. I always like to read this blog! God bless!
