Greeks used coins for currency. They put their leaders' faces on their coins so people knew who was in charge. Today we put our presidents' faces on money to show who runs our country and to honor our past presidents.
In Rome their military's legions were split into smaller units. Now our military is split into five branches: army, marines, navy, air force, and coast guard.
In Greece they had three types of columns: doric, ionic, and carinthien. Greeks used these columns to support buildings. Today columns are used for decoration and stability.
