Mithridates, he died old.

The line is from A. E. Housman’s poem “Terence, this is stupid stuff,” in A Shropshire Lad (1896). In the poem, the speaker answers a friend (“Terence”) who is criticized for writing gloomy verse. To defend the usefulness of bitter truths, he cites historical examples of people who built tolerance to poison—most famously Mithridates VI of Pontus, reputed to have taken small doses of toxins to immunize himself. Housman, a classical scholar steeped in Greek and Roman history, uses the anecdote as a learned illustration within a broader meditation on why dark poetry can still serve life.

Housman’s clipped statement about Mithridates’ longevity points to the paradox that controlled exposure to what harms can, over time, protect. In the poem’s argument, “poison” becomes a metaphor for painful knowledge, sorrow, or pessimistic art: taken in measured doses, it can toughen the mind against real misfortune. The line’s bluntness—almost like a note in a chronicle—underscores the speaker’s pragmatic stance: the value of grim verse is not to wallow in despair but to build resilience. The historical allusion also lends authority, suggesting that hard truths have a kind of medicinal function.
