1766 (see Constitution of Sweden). It meant the ultimate breakthrough of secular literature. Naturally, the impulses that invigorated Swedish cultural life had their origin in the European Age of Enlightenment. The main influences came from Germany, England and France, and these were reflected in Swedish literature. The Swedish language became enriched by French words, and ideas of liberalization were based on the English model. Swedish literature consolidated around 1750; this is considered the start of a linguistic period called Late Modern Swedish (1750 – circa 1880). The first great works of the age were those of Olov von Dalin (1708–1763), and in particular his weekly Then Swänska Argus, based on Joseph Addison's The Spectator. Dalin gave a sketch of Swedish culture and history using language which had an unprecedented richness of sarcasm and irony. In the 1730s and 1740s, Dalin was unrivalled as the brightest star in the Swedish literary sky. He was the first to refine the language for practical purposes, in comparison with the laboured poetry of the 17th century, and he was the first author to be read and appreciated by the general public. In the 18th century, Latin rapidly declined in popularity in favour of the national language. One of the first authors to aim his books directly at the general public was the world-renowned botanist Carl Linnaeus (1707–1778). Later key figures included the poets Johan Henrik Kellgren (1751–1795) and Carl Michael Bellman (1740–1795). The 18th century was also the century when female writers first gained widespread recognition. Sophia Elisabet Brenner (1659–1730), Sweden's first professional female writer, had started her career in the 17th century, but it continued into the following century. Later, Anna Maria Lenngren's (1754–1817) often satirical writings proved to have lasting influence, and it remains a point of debate to this day how exactly to interpret "Några ord till min k. Dotter, i fall jag hade någon" ('A few words for my beloved daughter, if I had had one') – are the exhortations to remain at home and not get involved in literature or politics serious or satirical? 19th century Romanticism In European history, the period circa 1805–1840 is known as Romanticism. It also made a strong impression on Sweden, due to German influences. During this relatively short period, there were so many great Swedish poets that the era is referred to as the Golden Age of Swedish poetry. The period started around
