Barbarossa’s Pike

On this day 5th of October 1162 the Emperor Barbarossa threw a tagged baby pike into a pond. Weighing 350 pounds, the same pike was caught and eaten in 1397, having lived for 235 years.

Source: The Gourmet's Companion by Ross Leckie (Edinburgh 1993) Actually Leckie gives the dates decades after Barbarossa's death so have adjusted the dates (from 1262 to 1162). Possibly file under myths and legends -

or fisherman's tales...
