Sun of May

The Sun of May (Template:Lang-es) is one of the national emblems of Argentina and Uruguay, and it is featured on the countries' flags. It is a representation of the Inca sun god Inti. The sun, called the Sun of May, is a replica of an engraving on the first Argentine coin, approved in 1813, whose value was eight escudos (one Spanish dollar). It has 16 straight and 16 waved sunbeams.

In 1978 the sun colour was specified to be golden yellow (amarillo oro), to have an inner diameter of 10 cm, and an outer diameter of 25 cm (the diameter of the sun equals $5/6th$ the height of the white stripe. The sun's face is $2/5th$ of its height). It features 32 rays, 16 undulated and 16 straight, in alternation and from 1978 it must be embroidered in the "Official Ceremonial Flag".

The specification "of May" is a reference to the May Revolution which took place in the week from the 18th to the 25th of May, 1810, which marked the beginning of independence from Spain of the countries that then formed the Viceroyalty of the Río de la Plata.
