Aiton's Encyclopedia (1910)
ka-lir’o-e, a name of frequent occurrence in Greek legend. Perhaps the most noted was Callirrhoe, the daughter of Achelous, a river god. She became the wife of Alcmaeon. Alcmaeon had slain his mother Eriphyle in Obedience to an oracle. He then left Argos that he might be purified from his crime in the water of the Achelous. Here he met and married Callirrhoe. She knew that Eriphyle had once possessed a magic peplus and necklace, and she was determined to have them for her own. Alcmaeon had left them in Arcadia. Much against his will he went after them to please his wife, but on his return was a maiden of Calydon. She wooed by Coresus, the priest of Bacchus. She rejected his suit. Bacchus, in punishment, sent madness upon the people of Calydon. An oracle declared that the plague could not be averted unless Callirrhoe was sacrificed upon the altar. But Coresus, about to perform the sacrifice, was moved by love of Callirrhoe and gave himself in her stead. Touched by his devotion, she took her own life near a well, which was called thereafter by her name. The name has been given by botanists to several species of poppy mallows, rose, red, cherry, lilac, and white, gathered by children from Minnesota to Texas. See Alcmaeon

What Has Changed in the Last Century
The myths retold in Aiton's Encyclopedia of 1910 stand exactly as they were: Callirrhoe the daughter of Achelous and the maiden of Calydon are literary figures, and nothing has happened to them since. Two things have moved. The Athenian spring that 1000 Classical Characters in 1900 flatly identified with the Enneacrunus is now a matter of open dispute among archaeologists, who disagree over whether the fountain house excavated southwest of the Acropolis is that of Thucydides or whether Kallirrhoe should be sought on the Ilissos; and the name has since been attached to something the writers could not have imagined, a small outer moon of Jupiter found in 1999 and named Callirrhoe. The poppy mallows Aiton mentions are still the genus Callirhoe, still gathered from Minnesota to Texas.
