At the beginning of the 12th century, Spiro was just one of the many towns growing up along the rivers and streams of the American Southeast. It possessed the foundations of an impressive ceremonial center, but so did other towns, some even in the general vicinity of Spiro, such as the Harlan site many miles to the north. However, the next 150 years would propel Spiro to fantastic heights, dominating eastern Oklahoma, western Arkansas, southwest Missouri, and heavily influencing the entire region east of the Mississippi River and beyond. Four things, all connected and intertwined, brought Spiro to greatness. These included internal stability, success in war, control of trade, and religious power. – La Vere, David, Looting of Spiro Mounds: An American King Tut’s Tomb
It is true that Spiro was not the only ceremonial center (meaning a place where hardly anything but religious ceremonies were supported) as the Harlan site was a very influential center. But, their reign ended around 1250 CE just as Spiro was gaining speed. In the early stages of settlement, Spiro was a bountiful place to live as the seasons were predictable and the land was easy to cultivate. There was a great diversity of subsistence available as well because of the region’s proximity to rivers and forests. Just like any rich place there was social stratification within Spiro which eventually led to a religious class that was specially selected to care for the ceremonies associated with the mound center. Priest-chiefs and nobles lived healthier lives than the commoners and even separated themselves via clothing. “Noblemen might wear large snake-like necklaces and cloaks made of feathers. Their earlobes were pierced, actually slit with a knife, and large round ear spools were inserted into the slits.” Spiroans also practiced skull deformation which is a process that is performed on babies when their skulls are still developing. One particular form of “cone head” deformation seems to be a form of identification for Spiroan traders, believes Frank Schambach. Meaning, if a neighboring trader met some cone headed folk, then they knew the items they were pushing were high quality. The commoners are not known to wear any form of jewelry but probably tattooed their bodies like so many American Indians in this period.
The mounds grew larger and larger as priest-chiefs died and were interred with their afterlife possessions. Just as in many cultures in Mesopotamia, priest-chiefs’ bodies were laid to rest in a house where their bodies would decay. After this process was complete, their bones were carried to a ceremonial mound and laid to rest there along with exquisite goods such as effigy pipes (towards the latter stages of Spiro as their wealth grew), pipes, pottery and copper plated items (such as the wooden mask with a sheet of copper laid over that was referenced in the first post of this series). One of the particular signals that archaeologists identify cultures by, are the pottery sherds. More specifically what was mixed in to the clay (temper) to increase the strength of the pottery.
The pottery found in Spiro mounds were numerous and varied, obviously. Spiroans were extensive traders, for example pottery from the Pueblo (Southwest) people were found. This pottery (Pueblo) is identified in part by their extremely sandy clay. In contrast, pottery produced by Spiroans lacked this sandy texture and were tempered with grit, bone or grog (crushed pottery). In some rare instances the pottery was tempered with conch shell but this was an exotic item. This is one of the methods archaeologists use to discern which pottery is exotic and which is local. This helps measure the magnitude of their influence in the region as well as establish a heritage for Spiroan descendants (Caddos claim this heritage today). Conch shells with exquisite engravings were found as well. These were used as containers and, just as most items still preserved at Spiro, were most probably used ceremonially.
The last materials extracted from the mounds that I will talk about are the lithics (stone tools). Just as the materials used to create the pottery helped identify their origination, the same goes for tools. The raw materials used for tools are mined from quarries that can be easily traced. Most of the tools found here can be traced to sources found in the Southern Ozarks which is sometimes referred to as Boone chert (full disclosure: Daniel Boone is my great^5 grandfather so I’m partial to the name). Other sources of chert found here are from Flint Hills, Ouachita Mountains, Red River Basin and the Texas panhandle.
Just like the ceramic and shell containers, archaeologists uncovered an embarrassing amount of immaculately produced projectile points. Many of these points were rarely used and seemed to have one purpose which was to be interred with very important people.
Now, there can only be the end. It was a great and powerful run but the sources for Spiro’s boom eventually dried up.
