Olof von Dalin (29 August 1708 – 12 August 1763) was a Swedish nobleman, poet, historian and courtier. He was an influential literary figure of the Swedish Enlightenment.
Background
Olof Dalin was born in the parish of Vinberg in Halland. His father was the parish minister. His birth name prior to knighthood was Dahlin. Olof Dalin's father had taken his name from his hometown, Dalstorp in the County of Älvsborg. He was closely related to Andreas Rydelius (1671–1738), Bishop of Lund, and he was sent at a very early age to be instructed by him. Carl Linnaeus was one of his fellow-pupils.
Career

In 1723, while studying at Lund University, he first accompanying his stepfather, Severin Böckman, to Stockholm and in 1726 he entered into public office there. Under the patronage of Baron Claes Rålamb (1682–1751) he rapidly rose to favor, and his skill and intelligence won him a golden reputation. In the 1730s, Dalin wrote plays for the theatre, inspired by French dramas and much admired by his contemporaries. In 1733 he started the weekly Svenska Argus, on the model of Joseph Addison's The Spectator, writing anonymously until 1736.
He became Royal Librarian (1737–39) and was later appointed Rikshistoriograf (National Historiographer) (1755–56). With the avowed purpose of enlarging the horizons of his cultivation and tastes, Dalin set off, in the company of his pupil, Baron Rålamb's son, on a tour through Germany and France, in 1739-1740. Upon his return, the shifting political life at home caused him to write his famous satirical allegories, Sagan om Hästen and Aprilverk (1738), that were very popular and inspired countless imitations.
His didactic epos of Svenska Friheten appeared in 1742. Hitherto, Addison and Alexander Pope had been his models. In this work he draws his inspiration from Thomson, whose poem, Liberty, he emulated.
On the accession of King Adolphus Frederick of Sweden in 1751, Dalin received the post of Tutor to the crown prince – afterwards Gustavus III. He had enjoyed the confidence of Queen Louisa Ulrika, sister of Frederick the Great of Prussia, while she was crown princess, and she now made him secretary of the Swedish Academy of Letters, founded by her in 1753.
