Many of the earliest books, particularly those dating back to the
1900s and before, are now extremely scarce and increasingly
expensive. We are republishing these classic works in affordable,
high quality, modern editions, using the original text and artwork.
Lovers of the Occult and the unusual will love this book. It gives
a deep insight into the ancient Japanese tradition of magic mirrors
and their connection to the Sun Goddess. In Japan mirrors had a
peculiar place in society and spirituality. Mirrors were often
decorated and surrounded with flowers like we see icons from the
West decorated, and some of them are told to have magical
properties. This book digs into the special properties. It seems
that due to an old technique some Japanese mirrors can present
patterns or images, not to the onlooker but at the mirror's
reflection in the room, if the light source is just right.
Rose of the Winds: the Origin and Development of the Compass-Card
By Silvanus P. Thompson
Excerpt
Although the construction of the compass lies outside the scope of
this inquiry, some preliminary considerations are necessary
concerning the origin of the compass itself; and these must be
stated briefly. The mariners' compass, as we know it to-day,
consists of a light circular disk or card, beneath which is
attached a magnetic needle or system of magnetic needles. The card
is provided at its centre with a small cap, by which it is poised
movably upon a pin. The whole is enclosed in a hollow box or bowl
covered with a flat lid of glass; and the compass box or bowl is
suspended within two hinged rings of brass to enable it to conserve
its proper horizontal position in spite of any tilting movement to
which it is subjected by the rolling or pitching of the ship on
which it is carried.
The card is divded out into thirty-two 'points' or 'rhumbs' of
equal angular breadth forming a rose or star, and to these are
affixed the initials of the names of the thirty-two points. The
magnet needle, or system of needles, is affixed to the card
parallel to the direction marked NS on the card, so that when left
to itself, the card, obeying the directive force which acts on the
needle, sets itself in a direction pointing (magnetically) North
and South; the several 'points' marked on the card then indicating
the several directions that the mariner may know in which way to
steer in order to follow his desired course. The card is also
usually marked at its North point with a fleur-de-lis or other
distinctive sign. The magnetic needle is controlled in its pointing
by the magnetism of the earth's globe.
It is no part of the present paper to enter upon the reasons for
the irregularities which are found to exist in the directive force
of the earth, and which produce those local 'variations' of the
compass which the mariner encounters everywhere. Neither is there
here any question considered as to the errors or perturbations due
to the presence near the compass of pieces of iron on the ship, nor
as to those due to the incidental presence of magnetism in the iron
of the ship's hull or fittings; nor, again, as to the means for
compensating those perturbations or correcting those errors.
The compass, as above described, has remained practically unchanged
in all essential particulars for...

Windham Press is committed to bringing the lost cultural heritage
of ages past into the 21st century through high-quality
reproductions of original, classic printed works at affordable
prices.
This book has been carefully crafted to utilize the original images
of antique books rather than error-prone OCR text. This also
preserves the work of the original typesetters of these classics,
unknown craftsmen who laid out the text, often by hand, of each and
every page you will read. Their subtle art involving judgment and
interaction with the text is in many ways superior and more human
than the mechanical methods utilized today, and gave each book a
unique, hand-crafted feel in its text that connected the reader
organically to the art of bindery and book-making.
We think these benefits are worth the occasional imperfection
resulting from the age of these books at the time of scanning, and
their vintage feel provides a connection to the past that goes
beyond the mere words of the text.
