Well, I’ve mentioned my aversion to cutaway views before. This was actually one situation where a cutaway view would be really cool if someone could figure out how to pull it off, but I admit that I wasn’t up to it. (During my research, I actually did come across one or two attempts by other illustrators at a cutaway view, but they were not very successful in my opinion.) The difficulty is that the path of the tunnel—an engineering marvel of its day—is so circuitous that it practically defies representation in two dimensions. This would be a great project for a video-based or interactive virtual tour, and I’d love to see someone capable tackle that.
As it is, I used it as an opportunity to emphasize the growth of the city of Jerusalem from David’s time to Hezekiah’s with a dotted line representing the tunnel’s underground route beneath the Old City. This illustration appears on page 1183 of the HCSB Study Bible.
