Celtic Triangles - Triquetra

A very popular symbol it seems,you will  run into these patterns in just about every tattoo shop you can ever hope to visit.  Most tattoo shops have plenty of stencils for celtic tattoos and some may even modify the design to your specs if they can.

Here is some info about celtic triangles in general as described by Wikipedia 

The triquetra (often, triqueta) is a tripartate symbol composed of three
interlocked vesica pisces, marking the intersection of three circles.
It is most commonly a symbol of the Holy Trinity (Father, son, Holy spirit)
used by the Celtic Christian Church, sometimes stylized as three interlaced
fish:

The triqueta symbol predates Christianity and was likely a Celtic symbol
of the Goddess, and in the North, a symbol of the god Odin. Although it
is often asserted that the triquetra is a symbol of a tripartite goddess,
no such goddess has been identified with the symbol. Similar symbols do
occur in some Norse and Celtic goddess imagery, but most likely represents
the divisions of the animal kingdom and the three domains of earth mentioned
above. Triplicities were common symbols in Celtic myth and legend, one
of the possible reasons Christian beliefs were so easily adopted by the
Celtic people.

The triqueta makes an ideal Christian symbol. It is a perfect representation
of the concept of “three in one” in Christian trinity beliefs,
and incorporates another popular Christian symbol, the fish, in its original
form of the vesica pisces. It is sometimes enclosed within a circle to
emphasize the unity aspect.

Celtic Spirals

The spiral is probably the oldest symbol of human spirituality. It has
been found scratched into rocks from thousands of years ago, on every
continent in the world. The religious significance can only be guessed,
but it has been found on tombs, and possibly has a connection with the
sun- the sun makes a spiral shape every three months in its travels. A
triple spiral motif found on Celtic tombs is drawn unicursally (that is,
in one continuous line), suggesting a cycle of rebirth or resurrection.
(this hypothesis is bolstered by the fact that many of these appear to
be deliberately placed where they catch the first rays of the sun on the
solstice).

In modern times, the spiral is still spiritually significant. It is the
symbol of spirit in Wicca, an emblem of the Goddess.

a strong spiral decorates this celtic work of art... and, it will look great tiling your toilet.

Celts and their raging hormones and I hear they covered their bodies in blue paint to look menacing... maybe they should have taken this approach. much more menacing

mr ice cast a spiral spell of celtic coolness, didn't quite work for him

Celtic Crosses - meaning

The Celtic cross (Ionic cross) has it’s roots in a pre-Christian variation
of the Solar cross. Examples of the Celtic cross date back as far as 5000
years BCE. Its origins are not known, but it was known to be an early
symbol of the sun god Taranis.

After the conversion of the Celtic people to Christianity, the Celtic
Cross became an emblem of the Celtic Christian Church. Irish legend holds
that the cross was introduced to Ireland by St. Columba, so it is sometimes
referred to as Columba’s cross, or the Ionic cross, after his monastery
on the isle of Iona.

Knights Cross

Yep, seems there is a celtic knights cross just like thereis a german one, actually, not, i hear some fool just made that up... anyway, sure you can create your own.

Yep, that giant thing may intimidate you all the way to church on a Sunday. I hear it shows some cereal christian honor and power through intimidation, i guess... hmmm, i would reconsider this choice. Christianity and intimidation only mixed well in the dark ages, Today other religions seem to be doing the intimidating.

  something to do with graves

a cross with a fireman, and a hat.

OK, no flames, but there is a cross... and a trendy knotted ring.

Probably one of the most popular symbols, 2 things put together, quite original and innovative.

Celtic Knott for tattoo

The Celtic Knot is one of the best known motifs in Celtic jewelry and
art. The delicate twists and turns are found in ancient stone art and
tattoos, in illuminated manuscripts- in fact, just about anywhere the
Celtic people have travelled. Similar designs exist in Norse culture,
and as far as China.

While there are many Celtic symbol guides available, especially those
that list every variation of celtic knot, many of the purported meanings
of the symbols are usually simply made up (most often to sell trinkets
and jewelry).

There are no known authentic knotwork designs meaning love or loyalty
or many of the other common meanings ascribed to the designs.

While many of the ancient designs certainly had some spiritually significant
meaning, these have been lost to the ages.

Velour knot... frilly

This lovely  cosmic pattern just winds and twirls into the realm of shear unconsciencess.  Without beginning or end it symbolizes that never ending road of BS travelled. This one is a keeper.

Shield Knot

The shield knot is an ancient and nearly universal symbol. The shield
knot has been used for thousands of years by a varfiety of cultures for
protection and warding.

While the common design is most often associated with the Celts and ancient
Norse, the most basic form is much older. The fourfold version at right
is Mesopotamian in origin and is associated with protective spells invoking
the gods of the four corners of the earth.

Later, it was used in the Kabbalah as a symbol of the Shema, the prayer/spell
to invoke the four Archangels; it is the origin of the “Qabbalistic
Cross” ritual still used today. This knot is sometimes referred to
as the “Earth Square” or St. Hans cross.

The Norse and Celtic versions of the knot are used for the same purposes
of protection but are related to the fourfold solar cross.

Triskele

The triskele, or triple spiral, a symbol closely related to the triquetra,
is a tripartite symbol composed of three interlocked spirals. The spiral
is an ancient Celtic symbol related to the sun, afterlife and reincarnation.
The example above comes from the Neolithic “tomb” at Newgrange,
where it is supposed by some to be a symbol of pregnancy (the sun describes
a spiral in its movements every three months; a triple spiral represents
nine months), an idea reinforced by the womb like nature of the structure.
The symbol also suggests reincarnation- it is drawn in one continuous
line, suggesting a continuous movement of time.

Triskeles are one of the most common elements of Celtic art; they are
found in a variety of styles in both ancient and modern Celtic art, especially
in relation to depictions of the Mother Goddess. They also evoke the Celtic
concept of the domains of material existence- earth, water, and sky, and
their interrelations.

Pictish Symbols

The Picts were a tribal people who lived in Northern Britain and Scotland
until about a thousand years ago. Their language is lost, except for fragments,
although they left behind a wealth of “picture stones,” large
monoliths carved with mysterious symbols whose meanings are mostly unknown.
There are about fifty major symbols. Some are easily identified as animals
or mythical creatures; others are completely mysterious, such as the “crescent
and V-rod” and the “double disk.” They may have originated
as tattoos or amulets. After the fifth century, most Picts converted to
Christianity, and most of their carvings reflect this change; many of
the so-called “Celtic” crosses dotting England and Scotland
are in fact Pictish stones.

Animals

Pictish animal signs may have been related to Gods and Goddesses, and
included boars, salmon, wolves, and birds:

Mythical creatures

Some of the most famous Pictish carvings are of monsters, mermaids, and
other sea creatures:

Enigmatic Symbols

Most unusual are the enigmatic symbols known as the “V-rod,”
“Z-rod,” and “double disks,” all named for their unusual
shapes. The V-rod is a bent arrow superimposed on a crescent; it is thought
by some to be a symbol of death:

The z-rod is found in combination with a serpent, a tomb/doorway, or
a double-sun (double disk), all possibly symbols of the solar cycle and
the afterlife:

Claddagh

The Irish Claddagh Symbol is named for the Irish coastal town of Claddagh
(pronounced “clah-dah”), where the ring design is attributed
to an ancient local legend. The now famous tale, about a townsman kidnapped
into slavery, who returns to present a ring to his true love, is one of
the most popular romantic tales of Ireland.

Despite the romantic story, Claddagh rings are a traditional token of
loyalty and friendship as well as romantic love. The Claddagh design usually
appears on rings, but is now used on all sorts of items, from jewellry
to napkins to family crests. The hands in the design represent friendship,
the heart, love, and the crown, loyalty. Various traditions ascribe different
meanings to the ring, depending on how it is worn- as a wedding ring,
it is worn on the left hand, with the heart pointed inward. As an engagement
ring, it is worn on the right hand, with the heart pointing inward; for
friendship, it is worn on the right hand, heart turned outward.

There is probably some relation between the claddagh and Norse “fede”
(engagement/betrothal) rings, which sometimes depicted hands clasped around
a heart.
