"Lachesis Lapponica: A Tour in Lapland" is a journal of one of the most important scientific explorations in history, written by scientists and the leader of expedition Carl von Linne. It was the first work to utilize Linne's ideas of nomenclature and classification practically. In the journey that lasted over six months, Linne passed over 2000 kilometers and described more than 100 earlier unknown species of plants. He also made notes on all the birds, rocks, and plats he met on his way. The memoir describes his ideas, notes on the journey, and an account of his discoveries.

Carl Linnaeus (1707 1778), also known as Carl von Linné, was one of the prominent biologists in the history of science. He was most famous for creating the binomial nomenclature, the system of naming organisms that is still used today. Born in Sweden, he received his formal education at Uppsala University, where he later lectured as a professor of medicine. He was a member and a leader of numerous exhibitions in Sweden and abroad. At the time of his death, he was one of the most acclaimed scientists in Europe.
