THE D TABLET
 

In the flag of Brazil the view is that of the southern night sky with the Hydra constellation at its navel:

Spica is the central star just above the 2nd O. Antares is not below the 3rd O but instead somewhat lower down to the left of β Scorpii (Grafias).

The little star below and a little to the right of the 2nd O is the Tail of the Hydra (Al Dhanab al Shuja). The Head of the Hydra (Alphard) is below M.

We can in the midcenter area below the outstretched Hydra constellation see the Southern Cross and also the tiny star further down which represents the South Pole (Dramasa).

Procyon is below the 1st O and there we will also find the 5 main stars in Canis Major.

The 6th star further down and below the Head of the Hydra is Canopus. To the left of the Scorpion are the 3 stars creating the South Triangle.

There is no sign of Argo Navis in the Flag of Brazil - unless we should regard the Hydra as its top. In order to better perceive Argo Navis (including Hydra) I have below coloured their stars with a bluegreen hue. The first point of Argo Navis is the great Canopus (α Carinae), its first star to rise at *95 (June 24, St John's Day).

... The Arabs in the desert regarded it as a test of penetrating vision; and they were accustomed to oppose 'Suhel' to 'Suha' (Canopus to Alcor) as occupying respectively the highest and lowest posts in the celestial family. So that Vidit Alcor, et non lunam plenum, came to be a proverbial description of one keenly alive to trifles, but dull of apprehension for broad facts ...
