They may not be completely ignorant, but it is plain that they parrot a
lot of the lost teaching without really understanding it; they have some
general idea, but the details are long lost. They know a kind of
lightning makes some machines go, but not how to construct a circuit.
They know that the Urth rotates, but not that it revolves around the
sun. They know that some statues are actually some sort of exalted
taxidermy, but nothing else about it. It's no stretch to presume that
irrigation is a similar summarization of terraforming.

The curvature of space bends the path of light just as it does the path
of material objects, so the spacewarp =can= explain the Sun being
visible as a distant star from Urth when looking back along the path
that the Whorl took. This same effect shows up in URTH with Yesod and
the ship, and to a lesser degree with the magic mirrors. This doubling
of the Sun is no more a mark of incompetence than the doubling of
Burgundofara, or Severian and Apu Punchau, or the various Tzadkiels are,
or the bilocation of the various Gardens.
If there are a few scientific details separating the hierodule's
spacewarp from what you would expect from a proper closed timelike path
in spacetime, I can only point to similar technical shortcomings in the
description of the function of the magic mirrors, the lifting principle
of the flyers, and the White Fountain's white hole nature, among others.
GW doesn't lets science get in the way of telling a story.
