Abstract
The riddle of the sigma is recast in a way that tries to differentiate fact from fiction as a basis for future/further discussion. By doing this, it is hoped that the role of the sigma as dominating the ubiquitous interactions below 1 GeV and its relation to the QCD vacuum can be clarified.
