“Aletheia’s Pearl” is a spiritual autobiography in the form of a personalized mythography. Pulter’s speaker describes the triumphs and challenges of her life through an account of her changing relationships with a range of personified figures: Aletheia (Truth), Joy, Peace, Patience, Hope, Faith, Sorrow, Fear, and Despair. An initial commitment to Aletheia, symbolized by a gift of a pearl, is followed by a youthful dalliance with Peace and Joy, the unwelcome appearance of Sorrow and Despair, and the belated company of Patience, Hope and Faith. Late in the poem, the speaker reveals that she lived thirteen years as a “maid” and thirty-three as a wife; this mature perspective informs the narrative of the poem, yet the precise relationship between the allegorical events of the poem and specific life-events (i.e.,marriage or the births or deaths of children) remains oblique.
One context for “Aletheia’s Pearl” is the invitation poem tradition, especially John Milton’s companion poems, “L’Allegro” and “Il Penseroso.” Pulter’s engagement with this tradition can be usefully explored through at least two different frames. First, most examples of the invitation poem, including Marlowe’s “The Passionate Shepherd to His Love” and Milton’s companion poems, position the speaker through heterosexual eroticism. Like Cavendish’s “Dialogue of Melancholy and Mirth,” “Aletheia’s Pearl” does not, and, further, Pulter’s speaker invokes female personifications defined primarily as mother-daughter pairs: Time and Truth, Peace and Joy, Faith and Patience. Second, Pulter’s speaker describes her youthful devotion to truth from the perspective of a later maturity. Milton’s “L’Allegro” and “Il Penseroso” are usually considered alternative models for living or for a poetic career; “Aletheia’s Pearl” does not propose a choice between joy and melancholy, but identifies these affects (and others) as part of a single “sad story” that develops over the course of the speaker’s life.
