An interesting rhyme in today's Times:-
King David and King Solomon
lived merry, merry lives,
with many, many concubines
and many, many wives.
But when old age crept after them,
with many, many qualms,
King Solomon wrote Proverbs
and King David wrote the Psalms.
There is a new book out, published by OUP and written by Prof. Eric Cline, called "Biblical Archaeology: A Very Short Introduction. Apparently in it he says that there is very little evidence that either David or Solomon existed. Fifteen years ago there was no evidence at all in either case but then, in 1994 the Tel Dan Stele was discovered - it had been reused as building material. Dating back to 842BC it tells of the defeat of Joram, King of Israel in the ninth century BC by a ruler in Damascus. The wording says that he "slew seventy kings" and it actually mentions The House of David. But of Solomon there is not a single piece of evidence outside of the Bible.
I am not a religious person but I do love the poetry, particularly that of the Authorised Version of The Bible, and particularly Psalms, Proverbs and Ecclesiastes. Whether or not David and Solomon existed in reality I don't think matters at all. After all, we know that the figures of Classical Greek Mythology never ever existed but it doesn't stop us enjoying the wonderfully poetic stories they tell.
