The word ænigma, which is derived from the Greek substantive ainigma, which the Latins call scirpus, signifies an obscure speech, or discourse, covering something common and universally known, under remote and uncommon terms. It is also frequently called riddle, probably from the Belgic readen, or the Saxon araethan — to interpret. Fra. Junius defines an ænigma to be an obscure parable or allegory, of which, he says, there are two kinds; the greater rendering the sentence more intricate and difficult of solution, by a multitude of words, and the lesser consisting of one or more words remote in their allusion […] The rebus is also ranked by some in the number of ænigmas. In a general sense, however, every dark saying, every difficult question, every parable, &c. may pass for an ænigma; hence obscure laws are called ænigmata juris.
