The constellation was proposed by the Dutch astronomer and theologian Peter Planzius on the insets to the world map of 1592  and was originally called Columba Noachi (translated from the Latin. - “Dove of Noah”), meaning the dove, who appeared to Noah as the news of the end of the Great Flood . The dove is located directly next to the constellation Ship Argo , which in the Middle Ages and New Time was sometimes called the Noah's Ark . According to one version, the name of the constellation may have a connection with ancient mythology, implying a dove released by Iason , which helped the Argonauts to get through the deadly Symptlegades  .
The constellation was represented in Bayer 's starry sky atlas “ Uranometry ” (1603)  , but since it was not included by the author in the map of the new constellations proposed by him, it is usually not assigned to the Bayer constellations. Augustine Roye formally approved it in heaven in 1679.
The main star of the constellation - Alpha Dove, which received its own name Fact in European culture - was known in Polynesian astronomy and was called Ana-iwa on the Society Islands  .
