The chronological criterion of indexing is followed by the criteria of security and higher or lower probability of Adickes’ dating. In the case of the RR dated with security, the indexing will depend on different degrees of precision in dating, in other words on the amount of assigned phases and consequently of the temporary extension included on them. In the first group of mentioned RR, the first ones will be those which include only one phase. They will be followed by those RR that include two phases. The third ones will be those with three phases and so on. Example Important note: If in the examples appear the same registers, it is not by redundancy, but due to the fact that the same R is related to more than one element in the place in which it was written up. It is clear that such data related to the work in which RR were written will be included in the indexes.
