On 21 September 1745 he delivered, on quitting school, a remarkable "departing oration" on epic poetry—Abschiedsrede über die epische Poesie, kultur- und literargeschichtlich erläutert—and next proceeded to Jena as a student of theology, where he drew up in prose the first three cantos of the Messias.
Finding life at that university not to his liking, he transferred in the spring of 1746 to Leipzig, where he joined a circle of young men of letters who contributed to the Bremer Beiträge.
He left the university in 1748 and became a private tutor in the family of a relative at Langensalza, where unrequited love for a cousin (the "Fanny" of his odes) disturbed his peace of mind.
For that reason he gladly accepted in 1750 an invitation from Bodmer, the translator of Paradise Lost, to visit him in Zürich, where Klopstock was initially treated with every kindness and respect and rapidly recovered his spirits.
[2] At this juncture Klopstock received from Frederick V of Denmark, on the recommendation of his minister Count von Bernstorff (1712–1772), an invitation to settle in Copenhagen with an annuity of 400 thalers, in the hope that he would complete Der Messias there.
The poet subsequently published his wife's writings, Hinterlassene Werke von Margareta Klopstock (1759), which give evidence of a tender, sensitive and deeply religious spirit.

He continued to live and work in Copenhagen, however, and next, following Heinrich Wilhelm von Gerstenberg, turned his attention to northern mythology, which in his view should replace classical subjects in a new school of German poetry.
In 1770, when King Christian VII dismissed Count Bernstorff from office, he retired with the latter to Hamburg but retained his pension, together with the rank of councillor of legation.
[2] His latter years he passed, as had always been his inclination, in retirement, only occasionally relieved by socializing with his most intimate friends, occupied in philological studies and taking scant interest in the new developments in German literature.
The French Republic sent him a diploma of honorary citizenship; but, horrified at the terrible scenes the Revolution had enacted in the name of liberty, he returned it.
[2] At the age of 67 he undertook a second marriage, to Johanna Elisabeth von Winthem, a widow and a niece of his late wife, who for many years had been one of his most intimate friends.
It has been said that Klopstock's hymn "Die Auferstehung" at the funeral of Hans von Bülow in 1894 gave Gustav Mahler the inspiration for the final movement of his Second Symphony.
[4] Klopstock published odes and hymns, including Der am Kreuz ist meine Liebe, which is in shortened and revised form part of the 2013 Catholic hymnal Gotteslob.
In addition to Die Gelehrtenrepublik, he was also the author of Fragmente über Sprache und Dichtkunst (1779) and Grammatische Gespräche (1794), works in which he made important contributions to philology and to the history of German poetry.
