Stub was born in Gummerup on the island of Funen, but his exact birth date is unknown. He was baptized at Verninge in Odense on May 17, 1705. The son of a tailor, he was able to attend the Latin school of Odense due to the generosity of noblemen who employed his father. From 1725, he studied theology at the University of Copenhagen. In Copenhagen he developed an interest in opera and music, nurtured by visits of touring opera companies from Italy and Germany. For a living, he worked as a poet and secretary for several noble families. After studying for almost 10 years, he left the university without a degree in 1734, and returned home. There he met Mette Cathrine Schousboe, a minister's daughter, whom he married in 1735. The couple lived at Mette's inherited farm which they were unable to manage well. As a result, its value soon declined, and the Stubs' living conditions became worse. Of the couple's four children only two survived childhood. In 1747, Stub's wife died aged 31. Five years later, Ambrosius Stub moved to Ribe, where he kept close company with Bishop Hans Adolph Brorson. Suffering from gout and an alcohol problem, he spent his last years there working as a teacher. He died in Ribe.
Work
Stub wrote his first poems as a 23-year-old student, but during his lifetime, only six of his works were published. Most of his work was properly written down, printed and published after his death. Because of this there is still some uncertainty about the correctness of the citations, and it is assumed that he has written more poems than those officially published. A first edition of his collected works was published posthumously in 1771. Later collections were assembled from songbooks, but the attribution of some anonymous poems and arias remains disputed. Stub's literary works have a wide variety of topics, comprising philosophical and religious poetry as well as drinking songs, love poems and occasional poems. His Du deylig Rosen-Knop can be read as a commitment to virtuousness: the withering rose is a symbol for perishable beauty, and only virtue persists. One of Stub's more famous poems Den kiedsom Winter gik sin Gang, is found in a truncated version in the anthologyHøjskolesangbogen. In this poem he describes the beginning of spring from the point of view of a sinister poet. Providence, however, holds more cheerful days for him to come, if he only keeps up his patience and fortitude. Stub's late work, written in Ribe, is influenced by pietism. Fear of death, Hell and the moral decline of the world become his primary topics of interest. He was also influenced by the German writer and musician, Johann Sigismund Scholze alias Sperontes. He wrote several religious hymns, like Jeg ser dit kunstværk, store Gud and Lyksalig endte da min frelser sine dage.
Death
Stub died in poverty on July 15, 1758. His body was buried in the cemetery of St. Catherine Priory in Ribe where a bronze monument designed by Per Kirkeby was erected in his memory on a grant by the New Carlsberg Foundation in 2003. It features a square frame in which a stump of a tree is surrounded by the remains of a capital with acanthus leaves, a fragment of a column, two rococo mirrors, and a number of wedges.
