A series of six programmes in connection with the current Exhibition of Gold and Silver at the British Museum. 5: Whose Wealth?
The Roman Empire's civil and military elite were rewarded with gold and silver for loyal service. However, it was the population at large that had to foot the bill through taxes, and it turned out in the end that the Empire could not afford its own defence.

Producer BETTY WHITE

A Yesterday's Witness series of six programmes with women of the First World War.

1916: Bob Murphy, a railway goods porter, was called up. His young sister Ann took over his job. She is one of several Liverpool women who describe, 60 years later, the trials and tribulations of moving in to work on the railways, in munitions factories, in offices, on the trams, in engineering works: a world previously reserved for men. They are typical of tens of thousands of women and girls throughout the country: they needed the money, the breadwinners were away and the jobs just had to be done. They weren't consciously working for women's rights - but struck a resounding blow just the same.
Narrator Gillian Reynolds
