one exists in large
quantities on the Earth's surface, and that is magnetite.
2) The discovery of the fact that steel or hardened iron can
be magnetised when rubbed against a magnetite crystal.
3) The discovery of the fact that the magnet, i.e. magnetised iron, as
it is hung or placed onto a pivot so that it can rotate freely, will
point to the same direction, or more precisely will align itself within
angle of a north-south axis.
4) Realising that this magnetised needle can be used as a means

following text were copied and adapted from
The Medieval Technology Pages by Paul J. Gans
"There seems to be a reference to a south-pointing spoon* in a
of the Han dynasty written in 83 AD. Another reference of the same
period states that the jade collectors of Cheng carried a "south
pointer" with them so that they would not lose their way [Gies, p. 94
- s. Sources below].
Magnetized needles used as direction pointers are attested in the
8th century AD in China, and between 850 and 1050 they seem to have
become common as navigational devices on ships. [Gies, p. 94]

and 1116 for mention of magnetized needles being used for geomancy and
1119 and 1122 for use as a mariner's compass. [White, p. 132]
first mention of the directional compass (as
opposed to magnets
themselves) in the Western world occurs in a long satirical poem (2700

also was a Man of God and lived in Paris for some time. We can thus
assume that Neckham knew Bercy's/Guyot's famous pope critical book
His book written
in Latin was more widely known than Guyot's old French poem.
The first mention of the
compass in the Muslim civilization occurs later in a Persian story of
1232-3. The first Arabic mention appears in 1242. White notes that the

One must consider two
aspects here which are not sustained by any evidence except the few
words of Arc Frode but
neglected because of the simple logic of the facts. It can be
that the instrument had already been known
by seafarers for a long
time and that its existence was also known to many people,
comparison would not have been understood by the readers of the
additional aspect is the fact that the few who possessed such an
instrument would have
most probably kept it secret as long as possible as they derived a
