How was come again sweet love published?

"Come Again, Sweet Love Doth Now Invite" is a poem by Sir Philip Sidney, part of his collection "Astrophel and Stella," which was published in 1591. The collection is considered one of the first Sonnet sequences in English literature, consisting of 108 sonnets and 11 songs. Sidney's work was published posthumously, and it drew inspiration from the Petrarchan sonnet tradition while exploring themes of love, longing, and desire. The poem itself reflects the courtly love tradition, expressing a deep yearning for love's return.
