My engineering husband questioned me about the liberties I take with Greek Mythology in my Turning Creek series. I told him it was creative license. He did not approve. The problem with engineers is that they want, nay need, things to fit into formulas. If you can turn the plot points into a color coded graph, even better.
His main complaint was that Thomas, the orphan Iris takes in after Lightning in the Dark, has the ability of speed and delivers messages. The Greek myth that these two traits fit best is Hermes.
Hermes was a god of Olympus, son of Zeus and Maia (one of the many women who fell for Zeus). Hermes was the herald and servant of Zeus.
In the world I created for Turning Creek, there are no Remnants of gods (that we know of). The gods, who reigned on Mount Olympus, required adoration and were accustomed to a certain level of power. They did not adjust to life in the mortal world after the Fall of Olympus and they faded from existence. In the world I have created, Thomas could not be the Remnant of Hermes because Hermes faded long ago, thus I borrowed Achilles for Thomas.
Achilles was a famous warrior in the Trojan War. I did a Mythology Mondays profile of Achilles with more detail. In the original myth, he was slain with an arrow to his heel.
I gave Thomas speed because it was a convenient power for him to have and assist Iris. I gave him Achilles’ weakness because I wanted him to have one.
Creative License. I wield it.
One of the fabulous things about mythology, and Greek mythology in particular, is that every tale has multiple versions. Thanks to the warring nature of the Greeks, Romans, and their many neighbors, Greek myths were adopted and adapted by different peoples and regions. Even the ancients had their own version of creative license.
If, like my husband, my liberties with the original myths make you roll your eyes and wonder if I did any research at all, I assure you, I did research. Sometimes, I apply creative license to whatever facts I find.
