Herculaneum: Archaeologists find diet of poor was rich

1 April 2013 Last updated at 20:23 BST

Sometimes called The Other Pompeii, Herculaneum is a vast site nestled in the shadow of Mount Vesuvius in Italy.

It too was destroyed by the volcano in the year 79 AD, and later excavated and it has now thrown up a treasure trove of secrets.

Among them, findings that the poor there lived a rich and varied life - richer, in fact, than many Italians do today.

A new BBC documentary takes a look at these new discoveries.

Erica Rowan, an archaeology PHD student specialising in Roman Food and Diet, helped to identify and analyse material found in the sewers.
