and I'd love to at least metaphorically wring the necks of the mediaeval Romans who destroyed it....

Shattered Marble Map Mystifies Puzzlers

An unintentional jigsaw puzzle made of marble, over two millennia old, and missing most of its pieces has defied scholars and puzzle-solvers for centuries. Measuring 60 x 43 feet and carved in the 3rd century CE, the Severan Marble Plan of Rome captured the groundplan of Roman architecture in minute detail, even down to staircases, but only 10 to 15 percent of the intricately carved map has been found. Excavations for Rome’s new subway line this year may soon unearth further pieces to the puzzle, according to an article from Discovery News.

Roughly on a scale of 1:240, the Severan Marble Plan consisted of 150 slabs mounted on what was once the interior wall of the Temple of Peace (now the exterior wall of the Church of Saints Cosmas and Damian). During the Middle Ages, the Plan was slowly destroyed, parts of it ground up and repurposed into building materials, pieces broken and re-broken over centuries. Some pieces just fell to the base of the wall and were buried by time. The holes where the slabs were once anchored to the wall are still visible.

Discovering history

Undisturbed artifacts will detail lives of Civil War prisoners

Nearly 150 years after it was left behind at a Civil War prison camp, the 3-inch clay pipestem still shows a Union soldier's teeth marks.

The pipe, whose stem features the name of its manufacturer, proves the resourcefulness of a prisoner who really wanted his tobacco. He fashioned the bowl from lead, possibly by melting rifle bullets.

No one knows what became of the unknown soldier at Camp Lawton, which during its short existence in south Georgia was the Confederacy's largest prison camp.

"His name his been lost to history but his story has not," said Kevin Chapman, who led a group of college students that found the exact location of the camp's slave-built stockade and, in the soil beneath tall pine trees, nearly 200 artifacts.

Those are the first of what is expected to be a treasure of artifacts that will bear witness to the lives of prisoners and the horrors they endured.

The site is remote and is on federal land, jutting into a state park as well, so it is largely undisturbed. It provides a wonderful opportunity to see into the lives of the people involved.
