Antinous (constellation)
Antinous is an obsolete constellation no longer in use by astronomers, having been merged into Aquila, which it bordered to the north.
The constellation was created by the emperor Hadrian in 132. Antinous was a beautiful youth loved by Hadrian, and also his erotic lover. Cassius Dio, having access to Hadrian's diary now lost, informs that Antinous died either by drowning or (as he himself believed) as a voluntary human sacrifice,<ref>Cassius Dio, Roman History (Epitome) LXIX 11.2-4.</ref> something supported by Lambert (1984).<ref>Template:Cite book</ref> The elevation to divinity meant that Antinous was to be a god in the heavens forever – Hadrian having named an asterism in the sky after him.
Tycho Brahe was originally given credit for inventing Antinous, but current finds include a celestial globe by the cartographer Caspar Vopel from 1536 that contains Antinous,<ref>Star Tales — Antinous, by Ian Ridpath</ref><ref>An Outline Sketch of the Origin and History of Constellations and Star-Names Template:Webarchive by Gary D.

In the following modern times, Antinous has been variously considered an asterism within Aquila or as a separate constellation, until the International Astronomical Union discarded it when formalizing the 88 constellations in 1922.
The IAU Working Group on Star Names approved the name Antinous for the star Theta Aquilae in 2024, after the obsolete constellation.<ref name="IAU-CSN-new">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
