Everyone knows a couple of things about leprechauns (aka lurachmain, lurican, leprechawn, lepracaun, leprechaun, lubberkin and lurgadhan). They’re small, tricky gingers that, if caught, will show you the money. One theory about the word’s origin is that it comes from luacharma'n (or luchorpán), the Irish word for “pygmy.” Another theory is that the word is derived from leath bhrogan, meaning “shoemaker.” Not as many people know but leprechauns usually find employment as cobblers or shoemakers. Presumably they make and repair the shoes of other faerie folk and Tuatha Dé Danann, because how else could they make money off each other if they all practice the same trade? And leprechauns make money. If you lay your eyes on one, don’t look away or they’ll vanish.
Although the Irish believe that leprechauns emigrated from the island of Fir Bolg, they’ve nonetheless become one of the most common stereotypical images of Eire, along with that Romano-British Englishman, Sanctus Patricius, whose saint day is (of course) today.
