In the field 0f Greek Lexicography, where the words derive the one from the other and the senses slide from one meaning to another, the encyclopaedia, as source of knowledge, IS enhanced into an organic part of the historic course of the term “dance”. The information sources present, however, a great dissemination as regards both time and objectives. Thus, we have tried to describe the meaning 0f “dance”, on an index based research in eight selected Greek encyclopaedias that span from 1898 to the present day, in order to: a find out ‘the way in which the encyclopaedists approach and interpret the term “dance”, and how they transmute it, and b. investigate the degree of convergence/divergence among the recommended works. it should be noted that for the better understanding of the entries studied so far, which refer to actual situations, It is necessary to know when and by whom they have been written. The remark s, descriptions and reasoning of the compilers can, undoubtedly, be evaluated, if we consider the actual time of their research and writing. In our case it covers the period of the first generation of encyclopaedias, that is the years between 1898 and 1950 as well as the critical phase of the second generation, spanning from the middle of 1964 to 1994 and leading to the new era of dance.
