In that distant era of ancient Rome, A handsome young man came to visit the ancient Rome emperor Tiberius, young people give the emperor a shiny metal cup, but the cup is not like gold so heavy. In order to finish this cup, the young man worked for many days and nights and it made from clay. The emperor saw it and he smiled, but was afraid of the shiny new metal will replace the gold and silver.And not long after, the emperor then quietly put the young man to kill, so for a long time the silvery things not be seen.Do you want to know what this is?
