What is Bards pessimism?

It was the pet name for shakespeare, meaning "minstrel & singer-poet".

Bards are poet/musicians. In olden days bards were usually employed by the ruling class. Bards told stories, usually of historical events, through their songs and music.

A bard was a lyric poet that was chosen by a higher person like a king or ruler. I found this out by reading 'The Hobbit'. By the way it was the best epic I have ever read!

Pessimism is a state of having no hope that one's troubles will end or that success or happiness will come ever. It also means a condition of having the belief that evil is more common or powerful...

It could be "ere" or "e'er".
