The Lemuria sunken continent stuff is interesting, especially as you say, he seems to have a certain admiration of water.
Also, in Roman mythology, there are figures called “lemures”. Here’s the wiki page on ’em: http://en.wikipedia.org/wiki/Lemures (it mentions a couple of “Augustan poets” right there in the first paragraph, which is a fun lil connection to his name).
One thing we can take for certain from that scene is that August is a lying liar who lies about temples and monkeys and Nepal and lemurs. I so wish he’d scratched his itchy nose right after telling Ruby those lies, coz that right there woulda been inconclusive evidence as to his Pinocchio-ness. 😛
