Here, however, we are met with the positive assertion that there is a very small star (of about the sixth magnitude) in the south, called Sigma Octantis, round which all the constellations of the south revolve, and which is therefore the southern polar star.
It is scarcely polite to contradict the statements made, but it is certain that persons who have been educated to believe that the earth is a globe, going to the southern parts of the earth do not examine such matters critically.
But if the earth is a globe, Sigma Octantis a south pole star, and the Southern Cross a southern circumpolar constellation, they would all be visible at the same time from every longitude on the same latitude, as is the case with the northern pole star and the northern circumpolar constellations.

Sigma Octantis (also called 'Polaris Australis') is found in the constellation Octans, and like I said, is just barely visible to the naked eye; hence, people don't make as much of a deal about it as they do Polaris!
The easiest way to locate the South celestial pole is with the help of the Southern Cross (or Crux), a constellation in the shape of a cross.
Note that Sigma Octantis is only visible from the Southern Hemisphere and Crux only from South of around 20 degrees North.

When Polaris will be the north star again around 27800 AD, due to its proper motion it will be farther away from the pole then than it is now, while in 23600 BC it came closer to the pole.
To find the south celestial pole in the sky at this moment, one is less lucky, as that area is a particularly bland portion of the sky, and the nominal south pole star is Sigma Octantis, which with magnitude 5.5 is barely visible even under a properly dark sky.
However that will change in the 80th to 90th century, when the south celestial pole travels through the False cross.
