Actually the add (356-323 BC) is just on the inner sleeve, not on the back cover or vinyl itself... at least not on my copy. Guess it was juts added to inform people of the birth and dying day of the Macedonian.
Epic! "epic awesomeness...and awesome epicness " 
This song should be tagged as Alexander The Great, that's what it says on CDs and Vinyls. But if you look at the CD booklet it says "(356-323 BC)" below the song title.
