In the poem Seven Ages (extract of As You Like It), why does the poet, Shakespeare, call life an eventful history?

It’s important to remember that when reading a play the ideas and thoughts of the characters aren’t necessarily the playwright’s own. In poetry, often the poet herself is narrating thoughts and feelings, but in drama that is rarely the case. So in this case, Shakespeare himself doesn’t call life an “eventful history”, Jaques does. It’s not clear that Shakespeare agrees with Jaques’s summary of life; in fact, the speech about the seven ages of man is extremely bleak in its articulation of all of life ultimately ending in decay and uselessness. Life seems pretty pointless to Jaques in that speech. Maybe Shakespeare felt that way too, but we don’t know. Jaques calls life an “eventful history” ironically: “eventful history” makes it sound like a true-life adventure story, when actually what he’s just described is a series of life stages, predictable and boring, adding up to nothing much and ending in hopeless nothingness. It’s as if he described this inevitable march to the grave as an “epic saga”, coldly funny in its overstatement.
