Strehlow's knowledge of languages and rapport with senior men like Loatjira, Tmala and (for Loritja) Talku enabled him to publish a major tract on the legends, beliefs, customs, genealogies, secret initiatory life and magical practices of the peoples on the Mission, called in German Die Aranda- und Loritja-Stämme in Zentral-Australien (The Aranda and Loritja Tribes in Central Australia). The book was published in instalments between 1907 and 1920 and came about as the result of correspondence between Strehlow and the German gentleman scholar Moritz von Leonhardi. To clarify certain confusions surrounding this work: it was written by Strehlow, edited by Leonhardi, and published in sections between 1907 and 1920 under the auspices of Frankfurt's newly established Städtisches Völkermuseum (Municipal Ethnological Museum). Thanks to Leonhardi's contacts with Prof. Bernhard Hagen at the museum, the printing costs were financed by the Anthropological Society of Frankfurt, at that time playing an important role in the cultural life of Frankfurt and supported by wealthy benefactors, some from Frankfurt's prominent Jewish families. In return, the museum obtained a major collection of artefacts and sacred objects at a reduced price, unfortunately largely destroyed in World War Two. These included the usual spears, boomerangs, woomeras, digging sticks, stone knives and everyday objects, but also tjurungas, ceremonial objects and decorations of various kinds which were usually destroyed when the ceremony was finished, kurdaitcha boots, pointing sticks and so on with a view to enabling Europeans to get a full and comprehensive picture of Aranda and Loritja people and their inner world in conjunction with the explanations in the book.
