Oak trees are found throughout the world, mostly in the northern hemisphere. Nations revere the tree, which is known as the “king of the forest.” The Celtic world, which is known for its connection to nature, has a particular relationship and fondness for the tree.
Background
Oak trees call several places around the world home. These trees
can live for 300 years and grow to be 40 meters (more than 131 feet) tall. Oak
trees produce acorns, which house the seeds for oak trees within their strong and
sturdy shell.
It is believed that the oak tree is connected to the movement of Mars.
When Mars is close to Earth, it stimulates oak tree roots. When it is far away,
the Sun is the primary promoter of oak growth. This is why the oak is one of
the largest and most powerful trees in the forest.
In Ireland, Derry,
which is Ireland’s fifth largest city, is named after the oak tree, as the Irish
word for “oak” is “Dair” or “Doire.” Another Celtic language has the word for
oak as “Duir,” which inspired the name “Druid.” Kildare is also named after the oak tree, which
translates to “Church of the Oak.” Duir is the seventh letter of the Ogham
language and is also the seventh month of the Celtic tree calendar.
Symbolism and superstition
The oak tree is symbolic throughout the Celtic world. It is
the national tree of Wales. The oak tree represents strength, honor, endurance,
and liberty. Ancient Celts saw the oak as a symbol of knowledge. It is believed
that doors made of oak wood ward off evil spirits.
Mythology
The oak tree is the tree that is most prone to being struck
by lightning. It is believed that this is the reason why it is most associated
with gods across several cultures.
The Druids believed that mistletoe, which was considered to
be a sacred and magical plant, grew on mistletoe. They believed it was placed
there during a lightning strike and that this specific plant was the most powerful
mistletoe plant there was. This mistletoe plant was removed from the oak tree by
the Druids using a golden sickle. The ceremony took place after the new moon
following the winter solstice, which is why it is closely associated with
Christmas.
Poetic and bardic inspiration
It is believed that one of the five magic trees of Ireland, the
Tree of Mugna, was an oak tree. This tree served as inspiration for bards and
poets. These bards and poets are said to have taken the tree down themselves
when it was threatened to be taken down by Christian monks. This was because
this tree, as well as the other magic trees, was seen as a symbol of paganism.
Uses
Several animals use oak trees as a place for food and shelter.
Squirrels bury their acorns, which come from oak trees, in the ground to stash
food away for the cold winter months. Oftentimes, they forget where they buried
their acorns, which leads to new oak trees growing in the places the acorns
were left.
Acorns are used for food for squirrels. Acorns were ground
down to be used as a replacement for grain in bread when times were hard.
Because the oak tree is so strong, it is often used in
construction. It is often used to make things like boats, houses, furniture,
fencing, and more. Anything where a strong wood is needed is typically made
with oak.
The timber is not the only thing the oak is good for. The
bark of the oak was used to tan leather. It was also mixed with the leaves of
the tree to create a tonic to cure digestive tract infections, rashes, wounds,
and burns.
