On the night of May 24–25, 1447, a thief named Anna Vögtli broke into the parish church of Ettiswil in Switzerland's Lucerne canton, smashed open the wooden tabernacle, and made off with the ciborium and a large consecrated host. Realising she could not sell the consecrated host, she dropped it in a meadow on the edge of the village as she fled.
Early the next morning a woman gathering herbs in the same meadow saw the host suspended a few inches above the grass on what appeared to be a network of golden rays. Seven small floral shapes radiated out from the host — the 'seven-petalled' Eucharistic image afterward associated with Ettiswil. She called the parish priest. The host was returned, but was broken in seven pieces in the recovery; the seven fragments have been preserved since.
The local bishop investigated and approved the cult. A magnificent late-medieval reliquary in the form of a seven-petalled gilt rose with the host fragments still set in the centre is venerated in the Ettiswil pilgrimage church to this day. The annual procession of the Blessed Sacrament continues. Anna Vögtli was put to death for the theft; her name survives in the local tradition.
