Hierapolis
Hierapolis was first excavated by the German archaeologist Carl Humann during June and July 1887. His excavation notes were published in his 1889 book "Altertümer von Hierapolis". His excavations were rather general and included a number of drilling holes. He would gain fame for his later discovery of the Pergamon Altar, which was reconstructed in the Pergamon Museum in Berlin.
