TumulusA tumulus (plural tumuli) is a mound of earth and stones raised over a grave or graves. Tumuli are also known as barrows, burial mounds or (in Siberia and Central Asia) kurgans, and may be found throughout much of the world. A cairn, which is a mound of stones built for various purposes, may also originally have been a tumulus. Tumuli are often categorised according to their external apparent shape. In this respect, a long barrow is a long tumulus, usually constructed on top of several burials, such as passage graves.
PyramidA pyramid (from πυραμίς pyramís) is a structure whose outer surfaces are triangular and converge to a single step at the top, making the shape roughly a pyramid in the geometric sense. The base of a pyramid can be trilateral, quadrilateral, or of any polygon shape. As such, a pyramid has at least three outer triangular surfaces (at least four faces including the base). The square pyramid, with a square base and four triangular outer surfaces, is a common version.
Spiro MoundsSpiro Mounds (34 LF 40) is an archaeological site located in present-day eastern Oklahoma that remains from an indigenous Indian culture that was part of the major northern Caddoan Mississippian culture. The 80-acre site is located within a floodplain on the southern side of the Arkansas River. The modern town of Spiro developed approximately seven miles to the south. Between the ninth and fifteenth centuries, the local indigenous people created a powerful religious and political center, culturally linked to the Southeastern Ceremonial Complex identified by anthropologists as the Mississippian Ideological Interaction Sphere (MIIS).
