the origin of tattoo

We can find an example of tattoo in the Neolithic, in fact the first tattoo were found on a mummy, but tattoos were born in Polynesia and the word tattoo came from "Tatau" that was the typical Polynesian tattoo. Tattoos were used to decorate body and to scare enemies. I like tattoo but not the big ones because I think that they are disgusting, I love little tattoo because I think that with tattoo you can express your identity so I'd like to have one.
