Brother Klaus's fast
From 1467, the Swiss hermit Niklaus von Flüe is said to have lived for nearly 20 years in the Ranft gorge on the Eucharist alone.
1467 CE · 46.87, 8.27 · status: disputed
The account
The authorities had him watched to test the claim. He is now Switzerland's patron saint.
The sceptical view
Total fasting for years is physiologically impossible; observers could not watch him at all times.
