Now, then, future

Every object is temporal: what it feels like now, what it used to mean, and what it can become next.

Now

Then

1612: The first published poet of British America (1612–1672) lived in Newtowne in the 1630s; The Tenth Muse Lately Sprung Up in America appeared in London in 1650 — a colonial woman’s voice the empire couldn’t ignore.

Future
