Arthashastra
तस्य अभिशस्त अङ्को ललाटे स्याद् व्यवहार पतनाय, स्तेयो श्वा, मनुष्य वधे कबन्धः, गुरु तल्पे भगम्, सुरा पाने मद्य ध्वजः ॥
The face of a Bráhman convict shall be branded so as to leave a mark indicating his crime:--the sign of a dog in theft, that of a headless body in murder; that of the female part (bhaga) in rape with the wife of a teacher, and that of the flag of vintners for drinking liquor.
