A history of the Magellanic Clouds and the European exploration of the Southern Hemisphere

TL;DR

This paper traces the historical discovery, naming, and scientific recognition of the Magellanic Clouds, highlighting their significance in European exploration and astronomy from pre-16th century to the 19th century.

Contribution

It provides a detailed historical account of how the Magellanic Clouds were known, named, and integrated into scientific discourse over five centuries.

Findings

The Magellanic Clouds were known before Magellan's voyage.

The name 'Magellanic Clouds' became standard only in the late 19th century.

European explorers played a key role in the recognition and naming of the Clouds.

Abstract

The Magellanic Clouds were known before Magellan's voyage exactly 500 years ago, and were not given that name by Magellan himself or his chronicler Antonio Pigafetta. They were, of course, already known by local populations in South America, such as the Mapuche and Tupi-Guaranis. The Portuguese called them Clouds of the Cape, and scientific circles had long used the name of Nubecula Minor and Major. We trace how and when the name Magellanic Clouds came into common usage by following the history of exploration of the southern hemisphere and the southern sky by European explorers. While the name of Magellan was quickly associated to the Strait he discovered (within about 20 years only), the Clouds got their final scientific name only at the end of the 19th century, when scientists finally abandoned Latin as their communication language.
