Time.

The early Victorian period is often romanticised in modern literature and film. The intellectuals in that time knew that their world was hellish and romanticised the medieval period.  Which was horrendous,  and in which people romanticised the classical period. In the classical period, they romanticised a Golden Age which may or may not have ever existed.

I pity the poor bastards in the future who will romanticised our age.

Seeing in mist and shadows,
Makes the stars shine brighter,
After lifetime's of darkness,
Endless evenings seem lighter,

Virgin lips and virgin shores,
Hold far sweeter treasures,
Than home's long open doors ,

We upon this Earth ,
Are born always to die,
Human Souls - like eagles -
Were made only to fly.
