Speaking of the constellations on the national flag, in fact, the most common constellation is the Southern Cross in the flags of all the countries on our earth, after all, not only the Brazilian flag has the existence of the Southern Cross, but also several other countries, such as Australia and New Zealand, Papua New Guinea.
So why do so many countries put the Southern Cross in the starry sky on their flags? In fact, the reason is very simple: the main religious beliefs in these countries are Christianity, and these countries are located in the southern hemisphere, where people can see the southern cross almost every night when they look up, which is the same as the people in the northern hemisphere who can see the big dipper as soon as they look up.
The Southern Cross, as one of the eighty-eight constellations in the celestial sphere, is actually the smallest constellation, its position is located between Centaurus and Mosca, there are four bright stars in the constellation, and the Big Dipper in the northern hemisphere is a highly recognizable constellation, and the main bright stars in the constellation are the γ, the two (α), the three (β) and the four (δ) of the constellation to form a cross... The cross is well understood, so it is not difficult to understand that this southern cross appears on the flags of many Christian countries in the southern hemisphere.
Of course, there may be some friends who wonder: it doesn't matter if other countries have a southern cross on their flag, but isn't it a joke that Australia's flag has a cross? Aren't Australians the descendants of the criminals exiled in Britain? It is also true to say that Australia at that time was indeed a place where British criminals were exiled, but people were also British colonies, so even if they were sinners, they were also Christian sinners, and now Australians are better to say that they are the descendants of Christian robbers, to put it bluntly, that is, thieves and thieves and grandchildren...
Since the main structure of the anime work "Saint Seiya" is derived from ancient Greek mythology, the Southern Cross in the plot is not so brilliant, so that in the plot of the canon, there is no chance to appear, but it still appears three times in the plot outside the canon:
In the theatrical version of "Saint Seiya", "Evil God Eris", because the Saint Seiya of the Southern Cross was resurrected by Eris, it is also known as the "Undead Saint Seiya", and the Southern Cross Undead Saint Christopher Kleist in the plot was eventually used as cannon fodder by the evil god Eris, and was used to attack the glacier of the white bird and received a box lunch gloriously offline.
In the resistance version of "Saint Seiya", there is also a Saint Seiya of the Southern Cross, that is, the father of the new generation of small strong leos, Cang Mo, who was originally so-so, but because of the light enemy, he was killed by the young Martian princess Sonia, and later Sonia died under the mouth cannon of Cang Mo, which is estimated to be a kind of retribution.
There is also a Silver Saint of the Southern Cross who was sent by the pseudo-Pope Saga to Japan with the Shield Seat and the Northern Corona Saint to assassinate Jodo Saori, and was eventually defeated and influenced by the Silver Lady Saint of the Peacock Constellation, Mayura.
