Thursday is named after Thor. He is thunder. Which somehow when I googled it came out Jupiter.The Romans were masters at sucking up the world as they saw it and spewing it out as Roman. I'm referencing this to Hecate's explanation of what Tuesday was about. Thor was the sky god of thunder and all that jazz.. I guess he was a friend or cohort of Mars. A Norse or Germanic concoction that according to Wiki leads back or forward to Jupiter.
