Star Globe by H. Hughes of London
- dated around 1920.
These globes were used by the
ship's navigator, in conjunction with his sextant, to plot the
ship's position at night. In modern times of satellite
navigation this is a timely and decorative reminder of days gone
by and is a handsome quality crafted piece to grace any maritime

the year 232 B.C., Captain Rata and Navigator Maui set out with a
flotilla of ships from Egypt in an attempt to circumnavigate the
Earth. It has been proved in principle that Captain Rata and
Navigator Maui could have known and charted their location, by
longitude, most of the time during that voyage.
Maui expedition was under the guidance of Eratosthenes, the great
scientist who was also the chief librarian of the library at
Alexandria. It is argued that this voyage could have demonstrated
Eratosthenes' theorem that the world was round, and measured
approximately 24,500 miles in circumference? One of the
navigational instruments which Maui had with him was a strange
looking "calculator" that he called a tanawa;
such an instrument was known, in 1492, as a torquetum. This
is the forerunner of many navigation instruments, such as the Star
Globe offered for sale above.
is a cave drawing of that tanawa in Irian Jaya, western New Guinea.
It has been suggested that Maui must have been looking at the
ecliptic to measure "lunar distance," in order to find
his longitude. Maui's tanawa was of such importance, that he drew
it on the cave wall with the inscription, deciphered in the 1970s
by epigrapher Barry Fell: "The Earth is tilted. Therefore,
the signs of half of the ecliptic watch over the south, the other
(half) rise in the ascendant. This is the calculator of
had just measured the circumference of the Earth, and the
circumference of a sphere is the same in all directions. We can
guess that Maui was thinking about this, because his cave drawings
also include a proof of Eratosthenes' experiment to measure the

rock and cave inscriptions from the Pacific islands, western New
Guinea, and Santiago, Chile, tell of an Egyptian flotilla that
set sail around 232 B.C., during the reign of Ptolemy III, on a
mission to circumnavigate the globe. The six ships sailed under
the direction of Captain Rata and Navigator Maui, a friend of
the astronomer Eratosthenes (ca. 275-194 B.C.), who headed the
famous library at Alexandria. Maui's inscriptions, as deciphered
in the 1970s by epigrapher Barry Fell, indicated that this was a
proof-of-principle voyage, to demonstrate Eratosthenes' theorem
that the world was round, and approximately 24,500 miles in

Vespucci said in a letter :
. . I maintain that I learned [my longitude] . . . by the eclipses
and conjunctions of the Moon with the planets; and I have lost
many nights of sleep in reconciling my calculations with the
precepts of those sages who have devised the manuals and written
of the movements, conjunctions, aspects, and eclipses of the two
luminaries and of the wandering stars, such as the wise King Don
Alfonso in his Tables, Johannes Regiomontanus in his Almanac, and
Blanchinus, and the Rabbi Zacuto in his almanac, which is
perpetual; and these were composed in different meridians: King
Don Alfonso's book in the meridian of Toledo, and Johannes
Regiomontanus's in that of Ferrara, and the other two in that of
Salamanca."2 The best "clock" to use for
reference, is the stars. In the roughly 27.3 solar days of a lunar
orbit, the Moon moves a full 360 degrees around the sky, returning
to its old position among the stars. This is 13 degrees per day,
or just over 0.5 degree per hour. So, while the rotation of the
Earth causes the stars and the Moon to appear to move from east to
west across the night sky, the Moon, because of its own orbit
around the Earth, fights back against this apparent motion, and
seems to move eastward (or retrograde) by about 0.5 degree per
hour. In other words, the Moon "moves" west only 11.5
degrees per hour.
