Until it settled the Constituent General Assembly of 1813, a stamp it didn't exist to legalize the government acts, because they came being used the stamps of the real weapons that were stamped in the documents during the Viceroyalty. In the face of such a necessity, the Assembly began to use an own stamp, inspired by a model that the Peruvian Antonio composed in 1812 Isidro of Castro for disposition of Bernardino Rivadavia and that he speaks to him been presented to the First Triumvirate.
Although there is not law neither I decree that establishes their use, the same one it was used 22 February of 1813 for the first time, when being stamped it with it seals in two citizenship letters sent by the Assembly, with the signatures of the president of the body, General Carlos María of Alvear and the secretary, Don Hipólito Vieytes.
It is considered that their fringe showed the legend "In Union and Freedom"; the existence of the same one is endorsed by the ordinance of 13 March of 1813, with which the General Assembly orders to the Supreme court to Be able to Executive the use of the same stamp, with the only difference that the inscription of the circle is the one of "Supremo Poder Ejecutivo de las Provincias Unidas del Río de la Plata"
The National Shield arose of this stamp, being considered that it passed to have the investiture of symbol of nationality, when the General Belgrano made it stamp in the banner blessed in Jujuy in May of 1812, and that then it was deposited in the Town council of this city.
Their definitive form was fixed in 1900 by Estanislao S. Zeballos, in those moments Secretary of State; and their archetype, settled down in 1944.
It possesses the characteristic it forms oval, with their field divided in two barracks: the blue superior, represents the Justice, the Truth, the Loyalty and the Fraternity; the white inferior, symbol of Purity, Faith, Nobility, Integrity, Stability and Obedience.
In the barracks inferior two arms skillful nudes, they intertwine their hands, representing the fraternal union of the men and of the towns, they sustain a pike symbol of the Authority, the Control, the Dignity and the Sovereignty in whose extreme and already on the superior field, a cap frigio is located that represents the Freedom, the Equality and the Sacrifice.
To both sides of the shield, two laurel guides, in symbol of Victoria and of Gloria, united under the heraldry with a tape knot with the national colors.
In the superior part, a nascent sun, in gold, with rays flamígeros and alternate rectums, represents the Truth, the Majesty and the Prosperity and it possesses the sense of a new Nation that arises to the universal concert, full of splendor and of glory, pure and radiant as the Sun whose desire is to live luminously, in eternal dawn.
