High Quality Content by WIKIPEDIA articles! Sailors` superstitions have been superstitions particular to sailors or mariners, and which traditionally have been common around the world. Some of these beliefs are popular superstitions, while others are actually better described as traditions, stories, lore, tropes, myths, or legends, sometimes with a Gothic fictional element.
