Outside its non-linear rules, nothing can manifest itself as a "unique event", worthy of being remembered and celebrated. Therefore the archive as a mirror of reality is also the set of rules that determines the memorial and aesthetic process that are to be remembered and registered.

title: Wooden canopic chest

description: Canopic chest from the collection of the Egyptian Museum of the University of Bonn.

The ancient Egyptian viscera box from the Ptolemaic period (ca. 300-100 BCE) has the function of a storage and protective container for the mummified organs of the deceased Her-ib-Djehuti, son of Pa-di-Usir.

The scenes on the four box surfaces represent in summary the rites around the revival of Osiris, which were for the deceased due to his identification with this god the condition for a living beyond existence. Furthermore, the dead person is connected to the cyclic solar cycle, whose regenerative phase takes place in the underworld.

title: LeCroy Bifurcated Stemmed

description: This small stone projectile point with the distinctive lobed base is known as a LeCroy Bifurcated Stemmed. LeCroy points were used as spear or dart points and date to the latter part of the Early Archaic period (c. 7000-6000 BC). LeCroy points are more well known from the western part of the state and into Tennessee, but can be found throughout the piedmont as well. LeCroy points share a similar base shape to St Albans side-notched points and may be the precursors to the later Stanly and Kanawha points. This example has been repeatedly resharpened before it was lost or more likely discarded. It was found at a multi-component site (31WA2199) in eastern Wake County, NC and is made from a metavolcanic stone commonly called rhyolite. It measures 2.6 cm long, 1.8 cm wide, and 0.5 cm thick. This model was constructed by David Cranford with 57 photos using the Agisoft Metashape software. (Credit: NCDNCR/OSA)

description: Iron Scissor Handle
UWG-1096.01: Bonner House Collection
Waring Lab, University of West Georgia
Scanned and Processed by: William Drumm, Public History Intern and Andrew Carter, Curator of Collections

This scissor handle was recovered from the campus of the University of West Georgia during an archaeological investigation of the Bonner House and Plantation.

Thomas Bonner came to Carroll County in 1829 with his father and brothers shortly after the county had been opened for settlement. The Bonner Family was among the original European-American settlers of Carroll County and first settled about six miles from Acorn Bluff, home of Chief William Macintosh, along the Chattahoochee River. Thomas Bonner owned the 202.5 acre Lot 99 from February 20, 1844 to July 28, 1865. Lot 99 would eventually be purchaed to build the 4th District A&M School that would become the University of West Georgia nearly a century later.

title: Blaschka Glass Model of Moon Jellyfish

description: Micro CT scan of a Blaschka model of a Moon Jellyfish from the D'Arcy Thompson Zoology Museum at the University of Dundee. 

DUNUC 9318 - Glass model of Aurelia aurita (Moon Jellyfish). Width=9cm.

D'Arcy Thompson acquired a set of Blaschka's exquistely delicate glass models in 1888. In Growth and Form, D'Arcy refers repeatedly to the art of the glass-blower, perhaps thinking of these very models.  

Scanned with a Nikon XT H 225ST micro CT scanner.  The resulting file is exported as an stl. and imported in to Zbrush.  

We'd love to hear from you if you download or print our models, especially if you use them in education and outreach.
