Alis grave nil is associated with the iconography of Cupid and appears in the tradition of love
emblems — illustrated
books of moral and amorous mottos that were enormously popular in the
Renaissance and that profoundly influenced the
imagery of love poetry. The phrase participates in the long tradition of wings as a metaphor for poetic inspiration, from Plato's
image of the winged soul in the Phaedrus through the Renaissance
conceit of the winged pen. Students should note that the phrase operates on two levels: literally, wings make weight irrelevant; metaphorically, love or inspiration makes the weight of suffering, duty, or
mortality feel
light. Related concepts include the Neoplatonic ascent of the soul on the wings of love, the image of the winged poet, and the contrast between the grounded body (grave) and the liberated spirit (nil grave).
