Some of the Egyptian artifacts on display at Glencairn, a mansion turned museum outside of Philadelphia.
In 1919, James Henry Breasted, archaeologist and founder of the Oriental Institute at the University of Chicago, embarked on a year-long trip through the Middle East. His goal was to identify research opportunities throughout the area, and to obtain artifacts to bring back to Chicago. The story (from a 2010 exhibition at the Institute) was told in Archaeology Magazine.
Artifacts from the early Spanish site in St. Augustine, Florida (associated with Pedro Menendez de Aviles, not Ponce de Leon) are being donated to the Florida Museum of Natural History at the University of Florida. U. Florida archaeologists have been excavating the site, and storing the artifacts, for many years, so it appears this will make the curatorial arrangement permanent, and perhaps provide a tax break for the owners of the site.
