A Valediction: Forbidding Mourning
Death as departure
Virtuous deaths were supposedly peaceful—the soul leaving willingly. Donne's using a good death as the model for a good goodbye.
The laity
Religious term—laypeople versus priests. Their love is sacred knowledge; ordinary lovers are mere congregants who wouldn't understand.
Ptolemaic astronomy
Trepidation of the spheres: a wobble in the outermost celestial sphere that astronomers debated. Huge cosmic event, but unlike earthquakes, it doesn't affect daily life.
Sublunary
Below the moon—the realm of change and decay in Ptolemaic cosmology. Everything beneath the moon's orbit is corruptible, unlike the perfect heavens above.
Gold leaf
Gold beaten into sheets so thin you can see light through them. The metaphor: their souls stretch but don't break, maintaining continuity across distance.
Drawing compass
The geometric tool with two legs—one stays fixed at center while the other traces the circle. The fixed foot actually does move: it leans and pivots as the other travels.
