Nor is my question about you personal beliefs or opinions. Rather, it is about whether the Book of Jonah is homiletic fiction or historical fact. You have asserted the latter. That being the case, the following is of great importance:
1) We have the remains of Nineveh. The city was about 5 kilometers at its widest dimension.
2) As an avid hiker, I can tell you that an adult can walk about 15 miles in one day. Thus, a city that would take three days to cross on foot would be about 45 miles across
3) Since 1 mile = 1.609344 kilometers, or, to round off, about 1.6 kilometers, a city 45 mile across at its widest point would have to be a bit over 70 kilometers wide.
4) Since Nineveh, at 5 K, was only 1/14th. of that 70 kilometers, the dimensions given in the Book of Jonah are hardly historical.
There are a number of possible explanations for this. One is that the Book of Jonah was historical, but full of excessive exaggeration. Of course, such exaggeration would cast some doubt on its historicity. Another explanation is that the Book of Jonah was not historically true, but was instead a fictional work meant to teach a moral lesson, much as were the parables of Jesus.
My question for you is this: If you accept the Book of Jonah as an historical account, how do you reconcile the dimensions of the city given in it with dimensions of Nineveh we know from its physical remains?
Please don't dodge this question.
