Sighs

Cf. Inferno IV, 25-27:

Quivi, secondo che per ascolatre,
non avea piante mai che di sospiri
che l'aura eterna facevan tremare. T
[Eliot's note]

In Limbo, the first circle of hell, Dante has found the virtuous heathens, who lived before Christianity and are, therefore, eternally unable to achieve their desire of seeing God (NA).
