The bank holiday dramatisation of the Odyssey was not unique, apparently. In 1981 American public radio presented an eight and a half hour version, and it has now (2004) been issued, probably on CD, but certainly for download from Audible.com. (not free like the BBC's Listen on Demand)
The publishers write:
When this groundbreaking serialized dramatization premiered on 320 U.S. radio stations, critics were unanimous in their praise, calling it “a feast for the ears” and “a magnificent blend of scholarship and showmanship.” It won numerous honors including the George Foster Peabody Award and the Pulitzer Prize for broadcasting. Never before or since has such an ambitious undertaking been attempted in public radio, and it was accomplished, not by a major network, but by a small nonprofit independent producer in Chicago. That was in 1981. It has been sitting on the shelf ever since.
Now, 22 years after its first airing, Blackstone is pleased to rescue this outstanding production from undeserved obscurity. These recordings have been mastered from unaltered air-checks of the original broadcasts. Here is all the drama, poetry, and excitement of Homer brought to life by skilled actors. For the fullest appreciation and understanding, each of the eight episodes is accompanied by a brief documentary illuminating a key aspect of ancient culture or Homeric art.
I have listened to the sample, and find that it is virtually a dramatic reading of a translation of Homer, so, much nearer the original than the BBC's. The download costs $39.87, and I doubt if any teacher would want the whole of it – a teacher would prefer just the set books for the current year – so perhaps this news is not very useful. Have a listen for yourself, though. I don't believe American accents would even be noticed by young folk, used as we all are to US TV and film imports.
