History & Etymology
The story of discovery and naming of the rare earth element Erbium began with Carl Gustav Mosander splitting old yttria into three new elements, yttria proper, erbia, and terbia (see the special Rare Earths page). In 1860 the Swedish chemist Nils Johan Berlin (1812-1891) denied the existence of Mosander’s erbia, and gave this name to his terbia. In 1878, Jean Charles Galissard de Marignac, professor of Chemistry at the University of Geneva, separated Berlin's erbia into two new earths, erbia and ytterbia (note). Marignac's erbia was the following year split by Per Theodor Cleve (1804-1905) into erbia proper and two new elements, which he named Thulium and Holmium (note). Analysis of Holmium showed later that it also contained Dysprosium.
The chemical symbol for Thulium was first Tu, but it was altered into Tm by the International Commission on Atomic Weights, since the symbol Tu was also in use for Tungsten (Wolfram, present day symbol W). The editors of Gmelins Handbuch regret this decision: the "m" does not belongs to the root of Thulium and is therefore not characteristic. John and Gordon Marks suggested in 1994 the symbol Θu (note).

Thule
To the ancient Greeks, Thule (also Tile or Ultima Thule) was the northernmost habitable region of the world. One of the first recorded sea journeys in the Atlantic was by Pytheas of Massalia, who sailed to England in about 325 B.C. from his Greek colony in what is now Marseilles, France (although he probably traveled over land to the port of Corbilo and sailed from there.) He wrote about his voyage in a book called About the Ocean of which no copies exist, but he is quoted in other works.
On maps, Thule usually appears north or northwest of England and Ireland or in the northernmost parts of Asia. It has been associated with early reports of Iceland, Norway, or the Shetland Islands. Pytheas's Thule was probably Trondheim, in Norway.
Cleve himself, and after him most chemical sources, write that Thule is an old name for Scandinavia, which is not the case.
