If there is a recurring pattern in human political affairs, it should be possible to perceive it visually in relation to the regular periodic framework. In the exploration which I have set out here, observers will be able to form their own opinions. The coloured letters are for reference and are deliberately non-sequential. If they are not considered to be significant, they are generally omitted. If the characterisation is unclear, they are ignored or left uncoloured, as are neutral comments.
Criticism is welcomed.
Summary I shall summarise the framework of the diagrams for those whose equipment may be unable to load and display them. Some services leave them off altogether sometimes, or at any rate leave them off for such a long time that they might just as well not have bothered. I have, with difficulty, kept the size of each cycle diagram below about 30kb. This paragraph must be included with any copy, printout or other reproduction of any of the works on this website.
