 When Laura Roslin is writing her diary, she mentions for the first  time a Roman god name, since she states its Mars Day (probably  Tuesday in the colonial calendar, since thats the day dedicated to  the god of war). We can assume they use both Mars and Ares (this  name was used in the webisodes The Resistance), as well as they  talk of Jupiter in later episodes instead of Zeus (The Eye of  Jupiter, Rapture). Laura Roslin also says for the first time that  one of their gods has got an specific influence area, which is war  for Mars. Later, in the episode Torn, Hot Dog states Athena is the  goddess of war and wisdom.
