Sailors also had a culture of items or practices that were believed to bring
good luck, or trinkets to ward off bad luck or the "
evil eye".
Cats ship's cat While
in many cultures, a black cat is considered unlucky, British and Irish sailors considered adopting a black "
ship's cat" because it would bring good luck. A high level of care was directed toward them to keep them happy. There is some logic to this belief: cats hunt rodents, which can damage ropes and stores of grain on board, as well as spread disease among passengers and crew. Research has backed up this superstition. Evidence published in 2017 by a
geneticist the
University of Leuven shows that Egyptian cats spread their
mitochondrial DNA through shipping lanes to medieval northern Europe. Preliminary results of that genetic study concluded that cats were also carried on trading ships to control rodents, and that practice was adopted by traders from other nations, including
Vikings in northern Germany around the 8th to 11th centuries. Some sailors believed that
polydactyl cats were better at catching pests, possibly connected with the suggestion that extra digits give a polydactyl cat better balance, important when at sea. Cats were believed to have
miraculous powers that could protect ships from dangerous weather. Another popular belief was that cats could start storms through magic stored in their tails. If a ship's cat fell or was thrown overboard, it was thought that it would summon a terrible storm to sink the ship and that if the ship was able to survive, it would be cursed with nine years of bad luck. Other beliefs included: if a cat licked its fur against the grain, it meant a
hailstorm was coming; if it sneezed it meant rain; and if it was frisky it meant wind.
Cormorants Cormorants, in some Scandinavian areas, are considered a good omen; in particular, in Norwegian tradition spirits of those lost at sea come to visit their loved ones disguised as cormorants.
Whistling Whistling on board a sailing ship is thought to encourage the wind strength to increase. This is regularly alluded to in the
Aubrey–Maturin books by
Patrick O'Brian. On boats and ships whistling was taboo as it was associated with coded communications between mutineers. The cook was usually excused, because as long as he was whistling, he was not stealing the food.
Klabautermann Traditionally, a type of
kobold or mythical sprite, called a
Klabautermann, lives aboard ships and helps sailors and
fishermen on the
Baltic and
North Sea in their duties. He is a merry and diligent creature, with an expert understanding of most watercraft, and an irrepressible musical talent. He also rescues sailors washed overboard. The name comes from the
Low German verb
klabastern meaning "rumble" or "make a noise". An
etymology deriving the name from the verb
kalfatern ("to caulk") has also been suggested. A carved klabautermann image, of a small sailor dressed in yellow with a
tobacco pipe and woollen sailor's cap, often carrying a caulking hammer, is attached to the mast as a symbol of good luck. However, despite the positive attributes, there is one
omen associated with his presence: no member of a ship blessed by his presence shall ever set eyes on him; he only ever becomes visible to the crew of a doomed ship. The belief in Klabautermänner dates to at least the 1770s.
Patron saints Sailors have had several
patron saints. According to his
hagiography,
Saint Nicholas calmed a storm by prayer.
Brendan the Navigator is also considered a patron saint of sailors and navigators, due to his mythical voyage to
St. Brendan's Island.
Erasmus of Formiae, also known as Saint Elmo, may have become the patron of sailors because he is said to have continued preaching even after a thunderbolt struck the ground beside him. This prompted sailors, who were in danger from sudden storms and lightning, to claim his prayers. The electrical discharges at the mastheads of ships were read as a sign of his protection and came to be called "
Saint Elmo's Fire". Thus, Saint Elmo's Fire was usually good luck in traditional sailor's lore, but because it is a sign of electricity in the air and interferes with
compass readings, sailors sometimes regarded it as an omen of bad luck and stormy weather. The
mariner's cross, also referred to as ''St. Clement's Cross'', is worn by many sailors to bring blessings.
Good luck deities There are many deities associated with protection of sailors and good luck for them. For example, a sculpture of "
Tian Hou (or
Mazu), queen of heaven and protector of seafarers", is held at the Yueh Hai Ching temple on Philip Street, off of the
Singapore River in
Singapore.
Lucky actions English folklore includes many
superstitions surrounding hot cross buns. If taken on a sea voyage,
hot cross buns are said to protect against
shipwreck. If hung in the
galley, they are said to protect against fire and ensure that all breads turn out perfectly. The hanging bun is replaced each year. It is often considered lucky to touch the collar of a
sailor's suit. Folklore developed suggesting that possession of a baby's
caul would bring its bearer good luck and protect that person from death by drowning. Cauls were therefore highly prized by
sailors. Medieval women often sold them to sailors for large sums of money; a caul was regarded as a valuable
talisman. According to
Pliny the Elder, if a woman was on a ship, and she stripped herself naked, she could lull a storm at sea.
Mermaids and mermen Mermaids usually are considered lucky, but not universally. In
Trinidad and Tobago, sea-dwelling mer-men "were known to grant a wish, transform mediocrity into genius and confer wealth and power." Mermaids appear in
British folklore as unlucky omens, both foretelling disaster and provoking it. Several variants of the
ballad Sir Patrick Spens depict a mermaid speaking to the doomed ships. In some versions, she tells them they will never see land again; in others, she claims they are near shore, which they are wise enough to know means the same thing. Mermaids can also be a sign of approaching rough weather, and some have been described as monstrous in size, up to . A
world-famous statue of the Little Mermaid, based on Andersen's fairy tale, has been in
Copenhagen,
Denmark since August 1913, with copies in 13 other locations around the world. Sailors would look for
mermaid's purses on beaches for signs of mermaids in the area. ==Lore, mythology, and stories==
