How did the lower classes fare in Ancient Rome?

First-century burial grounds near Rome's main airport are yielding a rare look into how ancient longshoremen and other manual workers did backbreaking jobs, archaeologists said Monday.

The necropolis, which spanned the late 1st century into the 2nd century, near the town of Ponte Galeria came to light last year when customs police noticed a clandestine dig by grave robbers seeking valuable ancient artifacts, Rome's archaeology office said.

Most of the 300 skeletons unearthed were male, and many of them showed signs of years of heavy work: joint and tendon inflammation, compressed vertebrae, hernias and spinal problems, archaeologists said. Sandy sediment helped preserve the remains well.

Also excavated was a skeleton of a man whose lower jaw was fused to his upper jaw.

Study indicated "how for all of his life this individual was fed, likely through the care of his family" with liquids or semisolids "introduced through a hole made through his teeth," the archaeology statement said.

The man lived into his 30s, a decent age at the time. Experts took that as evidence that the lower classes cared for the disabled.
