Now that you've sampled, there's a link near the bottom to all previous posts (although the first few are rudimentary and rough, as I was climbing the ol' learning curve). But they all have descriptive titles, so you can pick whatever interests you. If flattened cities are compelling, try #13: it's Sodom and Gomorrah, but I forgot the title!
Really I dont think the destruction of Jericho was not a factor, although Joshua did not play around. I had seen the thread every day and just decided to take a look. I wasnt expecting so many images, but back in those days that was about all you could paint without being accused of blasphemy of some sort.
