In Irish folklore, rainbows symbolize success. That is as a result of leprechauns cover a pot of gold on the finish of each one. Not solely that, however that the pot of gold is guarded by a tough leprechaun. The legend goes like this:
As soon as upon a time, the Vikings lived in Eire, looting and plundering as they happy, then burying their ill-gotten treasures everywhere in the countryside. Once they finally departed from the Emerald Isle, they inadvertently left behind a few of their booty, which the leprechauns discovered.
Now, the leprechauns knew the Vikings had gotten their treasures by means of stealing, which was fallacious. This unhealthy conduct made the leprechauns distrust all folks, Viking or not.
With a view to guarantee no people might take what they now thought-about their gold, the leprechauns reburied it in pots deep underground everywhere in the island. When rainbows seem, they all the time finish at a spot the place some leprechaun’s pot of gold is buried [source: Mystical Myth].
Here is the catch: Believers who’ve looked for the legendary pot o’ gold all the time find yourself stymied, as a result of they will by no means discover the rainbow’s finish (severely, it is a matter of physics).
