Unfortunately history is full of horrible events and those ones are remembered by the great atrocities caused in those years. Happy happenings are difficult to find in history books...

By the way, year 657 BC Terpander, modified old tunes and modified the lyre by adding 3 strings more to the instrument. (Music history is full of good news, music is the universal language but who was the first musician?) There are things we will never know, however there are many people who did important things and are still unknown; we must be very thankful to the ancient folks.
