Edgar Allan Poe's "To Helen"

 Edgar Allan Poe (1809–1849) was one of the most influential figures in American literature, widely recognized for his mastery of Gothic fiction, horror, and detective stories. He was born on January 19, 1809, in Boston, Massachusetts. His father and mother, both professional actors, died before the poet was three years old. He was taken in by the Allan family (John and Frances Allan) as a foster child in Richmond, Virginia, and adopted the name as his middle name. However, his relationship with his foster father was often strained. John Allan, a prosperous tobacco exporter, sent Poe to the best boarding schools and, later, to the University of Virginia, where Poe excelled academically. After less than one year of school, however, he was forced to leave university when Allan refused to pay Poe’s gambling debts.

Elegy: Thomas Gray's Elegy Written in A Country Churchyard

 An elegy is a poem of sorrow or mourning for the dead; also, a reflective poem in a solemn or sorrowful mood.  The adjective ‘elegiac’ is used to describe poetry that exhibits the characteristics of an elegy.

Well-known elegies lamenting the death of a particular person include John Milton's Lycidas (Edward King), P.B. Shelley's Adonais (John Keats), Alfred Lord Tennyson's In Memoriam (Arthur H. Hallam), and Walt Whitman's When Lilacs Last in the Dooryard Bloom'd (Abraham Lincoln). Perhaps the most famous elegy, Thomas Gray's Elegy Written in a Country Churchyard, is a solemn, meditative poem mourning not the death of a person, but the passing of a way of life. Closely related terms of elegy are monody, threnody, and dirge.
