The Picts are often said to have tattooed themselves, but evidence for this is limited. Naturalistic depictions of Pictish nobles, hunters and warriors, male and female, without obvious tattoos, are found on monumental stones. These stones include inscriptions in Latin and ogham script, not all of which have been deciphered. The well-known Pictish symbols found on standing stones and other artifacts have defied attempts at translation over the centuries. Pictish art can be classed as "Celtic" and later as Insular. Irish poets portrayed their Pictish counterparts as very much like themselves.
