This feast day marking the legend of the Seven Sleepers, a group of companions who hid in a cave outside of Ephesus to escape
Roman emperor Decius’ persecution of Christians and emerged three-centuries later, also recalls one of the oldest and widespread artefacts of forecasting and weather lore (see also
