The Schwurhand (German pronunciation:[ˈʃvuːɐ̯hant], "swear-hand"; Dutch: spreekgebaar) is a heraldic charge depicting the hand gesture that is used in GermanicEurope and neighbouring countries, when swearing an oath in court, in office, or in swearing-in. The right hand is raised, with the index finger and middle finger extended upwards; the last two digits are curled downwards against the palm. The thumb is shown slightly curled or raised.
Traditional use
The use of the gesture dates back many centuries. Recruits of the Pontifical Swiss Guard at the Vatican City use the sign when swearing their oath of allegiance to the Pope, in a ceremony performed on 6 May every year since the Sack of Rome in 1527. The use of the three digits is said to symbolise the Holy Trinity.[1]
