The entire tatoo set is composed by 63 box wooden boards, on which devotional symbols, images of the Virgin or of the Crucifix, illustrations of certain Saints and, sometimes, secular images were printed on. People that came to Loreto in pilgrimage often required tattoos on their arms, to certify their participation to the religious rituals of the Church.Tattoos were exclusively made by 4-5 local families, handing down from father to son the skills of that art and the instruments, too. They injected under the skin a blue-turquoise substance, that gave permanent signs; they did it by a rude instrument called “picchetta”, which was formed by 3 needles linked together on their top.The blue liquid was used since the end of the XVI century, when Sixtus V was the Pope; it has been used for the entire 1800 and it definitely disappeared only in 1940-1950, even if it was prohibited by local authorities since 1860 for sanitary reasons.”
