A chapter that only knows its own name after it ends.
means A distinct stretch of time marked by particular characteristics, events, or a dominant figure or idea.
from From Latin 'aera,' meaning a number used as a basis of reckoning — itself the plural of 'aes,' bronze or money, perhaps from counting tokens or items in a list. Late Latin took this sense of 'a starting point for counting' and applied it to chronology, the fixed moment from which years are numbered. English borrowed it in the 17th century, and the word slowly widened from a precise calendar anchor into the loose, sweeping 'age' we mean today.
