Portugal
The five dot pattern occurs on the five shields (themselves arranged in a quincunx) on the flag of Portugal, which represent the five Holy Wounds inflicted upon Jesus during his crucifixion. In American and Canadian prisons the tattoo is worn by many Portuguese-North American inmates. This tattoo was also sometimes formerly worn by members of the Portuguese army on the hand or shoulder. It is also prevalent as a Portuguese-American and Portuguese-Canadian street tattoo.
