The refined composition, painted around 1615, depicts an episode from Torquato Tasso's Gerusalemme liberata, a composition that enjoyed extraordinary success in the field of pictorial production and whose first editions were illustrated by images conceived by the Genoese Bernardo Castello. Even in the library of Paggi, a cultured and up-to-date artist, there was a copy of Tasso's poem.

In the work, among the most early representations of the literary subject made locally, the warrior Rinaldo is depicted holding the mirror to the beautiful Armida, intent on styling her hair, accompanied by a putto with a bouquet of flowers. Among the bushes on the left emerge the Crusader knights Guelfo and Ubaldo, sent to the Isola della Fortuna to make Rinaldo come to his senses from the love spell of the sorceress Armida.
