I've just mentioned over ont' Holy Thread that yesterday evening I went to hear Terry Waite speak. One of the stories he recounted of his horrific time as a hostage in Beirut was about Penguin books - and how that little bird logo had proved to be of great help to him.
One of his guards was a kindly man, more humane than the others and, at no little risk to himself, tried to get some books for his English prisoner. This man had realized that lack of reading material for several years had been a particularly cruel deprivation for someone like Waite. Unfortunately, the guard's understanding of written English was limited, and his choice of books - which was quite random - proved to be bizarre. Waite said the absurdity of some of the volumes brought to him - which included
Great Escapes and
A Manual of Breast Feeding (unillustrated) - actually helped him stay sane. Keeping a sense of humour proved as beneficial in the dreadful circumstances as did his memory of old prayers.
In the end, however, Mr Waite somehow managed to get across to the guard that any book which had a penguin on its cover would be OK. This worked and subsequent offerings were more suitable.
How's that for the power of the symbol, especially that of the famous little bird on an orange background!
