The traditional seal of the Knights Templar shows two knights riding on one horse on one side and a representation of the Church of the Holy Sepulchre (in Jerusalam) on the other.
This is a reminder that the Order was originally established as the Poor Fellow-Soldiers of Christ and of the Temple of Solomon (Pauperes commilitones Christi Templique Salomonici), commonly known as the Knights Templar; or the Order of the Temple (Ordre du Temple or Templiers); or simply as the Templars.
In Britain the two knights on one horse was not used. Instead the Agnes Dei (the Lamb of God [Jesus Christ]) was used. Typical are those in the British Library:
Aymeric de St Maur, Master of the Knights Templar in 1200-1228
Robert of Sandford, Master of the Knights Templar in 1231-1247
The Templars were the most famous of the Christian Military Orders during the Middle Ages and its revival in the 18th century is a mark of its enduring appeal.
The Arms of the Order consist of a silver shield with the Cross of the Order, surmounted by a royal helmet crowned in gold and surrounded by the Collar. The supporters are two angels in dalmatics bearing the cross of the Order, holding the Great Banner and the War Banner of the Order. The pavilion is purple edged in ermine and topped with a golden crown:
Another simpler form of the Arms consists of the same shield surmounting two crossed swords, surrounded by the collar and surmounted by a silver helmet with a white feather:
These two forms of the Arms also have a white strip bearing, in black, the motto of the Order:
"Non Nobis, Domine! Non Nobis Sed Nomini Tuo Da Gloriam."
Not unto us O Lord not unto us but to your Name give glory
(Psalm 115: verse1}
The Great Banner (its main flag) of the Order, called Beaucéan (Baucennus) is white, bearing the Cross of the Order touching the edges:
The War Banner is a pallet in nine parts [alternate vertical stripes], white and black:
The banner of the Grand Priory of Wales is this:
Another emblem used in the Order looks like this:
Without the crown the emblem is:
