It should be noted that the Craig Mound at the Spiro site held the greatest concentration ever uncovered of similar ceremonial drinking dippers. In fact, over 500 engraved and non engraved conch shells were uncovered from this mound in the 1930’s, more than the total known for the entire rest of America combined! Many of these fantastically engraved large cups as well as gorgets exemplify much of what we know of the iconography of the Southeastern “Southern Cult”. A massive project was undertaken by Dr. Jim Brown and Dr. Philip Phillips to record these engraved shells and study their meanings, achieving fruition in the mammoth six part set of volumes through the Peabody Museum Press entitled “Pre-Columbian Shell Engravings from Sprio”. This monumental work created an unprecedented body of knowledge and would be of interest to anyone wanting to know more about these incredible objets d’art.
