Pastoral love poems have a rustic setting and portray the lovers as shepherd and shepherdess. They includes the invitation to love, praise of the beloved, emblematic blazons (lists of the features of the beloved, with each feature compared to an object in nature), courtship and wedding poems, and songs of separation, longing, and reunion.
Song of Solomon is a collection of pastoral love poems.
