The first humanist Albrecht von Bonstetten wrote several "Lives of Saints" that the oldest dates back from 1481.

By a divine miracle later she returned home and retreated to a cave where she found in her hermitage, the error was cleared up, but Ida wanted to continue dedicating her life to God as a hermit.

Later, her repentant husband had a hermitage built for her in Au, near the Fischingen monastery, where she lived until her death on 3 November 1226 and died in the name of holiness and was venerated as a saint before 1410.

[4] In 1704 the legend of Ida was reconstructed by the abbot of Fisching Franz Troger[1] with local data (Lake Lucerne): In 1724 Pope Benedict XIII granted her cult for the entire Diocese of Constance.

A little south of Fischingen Abbey, on a 976-meter-high mountain in the area of the Kirchberg community, there is a small pilgrimage site, St. Iddaburg (966 m).
