In 2012, physicists and astronomers celebrated the hundredth anniversary of the detection of cosmic rays by Viktor Hess. One year later, in 2013, there was first evidence for extraterrestrial high-energy neutrinos, i.e. for signal which may contain key information on the origin of cosmic rays. That evidence is provided by data taken with the IceCube neutrino telescope at the South Pole. First concepts to build a detector of this kind have been discussed at the 1973 International Cosmic Ray Conference. Nobody would have guessed at that time that the march towards first discoveries would take forty years, the biblical time of the march from Egypt to Palestine. But now, after all, the year 2013 has provided us a first glimpse to the promised land of the neutrino universe at highest energies. This article sketches the evolution towards detectors with a realistic discovery potential, describes the recent relevant results obtained with the IceCube and ANTARES neutrino telescopes and tries a look into the future. : 19 pages, 16 figures.
