<P> The reactions of professional archaeologists to archaeoastronomy have been decidedly mixed . Some expressed incomprehension or even hostility, varying from a rejection by the archaeological mainstream of what they saw as an archaeoastronomical fringe to an incomprehension between the cultural focus of archaeologists and the quantitative focus of early archaeoastronomers . Yet archaeologists have increasingly come to incorporate many of the insights from archaeoastronomy into archaeology textbooks and, as mentioned above, some students wrote archaeology dissertations on archaeoastronomical topics . </P> <P> Since archaeoastronomers disagree so widely on the characterization of the discipline, they even dispute its name . All three major international scholarly associations relate archaeoastronomy to the study of culture, using the term Astronomy in Culture or a translation . Michael Hoskin sees an important part of the discipline as fact - collecting, rather than theorizing, and proposed to label this aspect of the discipline Archaeotopography . Ruggles and Saunders proposed Cultural Astronomy as a unifying term for the various methods of studying folk astronomies . Others have argued that astronomy is an inaccurate term, what are being studied are cosmologies and people who object to the use of logos have suggested adopting the Spanish cosmovisión . </P> <P> When debates polarise between techniques, the methods are often referred to by a colour code, based on the colours of the bindings of the two volumes from the first Oxford Conference, where the approaches were first distinguished . Green (Old World) archaeoastronomers rely heavily on statistics and are sometimes accused of missing the cultural context of what is a social practice . Brown (New World) archaeoastronomers in contrast have abundant ethnographic and historical evidence and have been described as' cavalier' on matters of measurement and statistical analysis . Finding a way to integrate various approaches has been a subject of much discussion since the early 1990s . </P> <P> For a long time I have believed that such diversity requires the invention of some all - embracing theory . I think I was very naïve in thinking that such a thing was ever possible . </P>
