Australian Anthropologist Carole Muller researched various aspects of Nusa Penida in 1989, and reported on her findings in a publication entitled 'Nusa Penida, an adventure in 1990', published 2013. Muller discusses aspects of history and banishment to the island, the fate of the blacksmiths (Pande Wesi), the Bali Aga on Nusa Penida, and reports on her trip to Lembongan and various villages on 'Nusa Gede', and gives a description of the main temples, of which Pura Dalem Ped is the most important one. For her contribution on Nusa Penida textiles & Pura Dalem Ped, see elsewhere on this site. Below article is dedicated especially to Pura Batu Medahu and contains selected text from her book, which includes a great number of historical black & white photographs (not published here).
