Well, the Suez canal is a rather straightforward design as opposed to the Panama canal, read, it is just a big trench full of water connecting two seas that connect two oceans.Did the technology to build such a canal actually exist back then, though?
SO in theory it should have been possible, maybe with a few dams to feed water into the stretch of land between the two seas and some digging.
Methinks they'd need lots and lots of workers for a long time though.
