Antoine Banier was the coiner of the term "involuntary celibacy" in 1739. He was a French clergyman born on 2 November 1673 and passed away on 2 November 1741 and described inceldom as a form of imprisonment with his usage of the term "yoke". He also described it as a form of suffering and anguish through his usage of the word "groan". The unabbreviated form of incel was coined in the following excerpt from The Mythology and Fables of the Ancients, Explain'd from History, Volume 3:
The custom of the Ancients in their marriages was quite different from that of the age wherein we live: large gratifications were given to the young ladies whom they were to marry, and even to their parents, whereas it is very rare now-a-days for one to marry a woman without a portion. Homer and several others, mention this Custom, and would to God it were still in Fashion: How many young Women who groan under the Yoke of involuntary Celibacy, would find Husbands to make them happy, did not the Avarice of those husbands reduce them to the calamities wherein ixion was involved.

The "calamities of ixion" refers to the mythical Greek King of Thessaly, Ixion, who refused to pay the bride-price owed to his father in law, leading to Ixion eventually treacherously murdering the father-in-law, becoming the first kin-slayer and thus an outcast. Banier is referring to the ancient custom of bride price (man paying the woman's family to be married) as being preferable to the contemporary European custom in his own era of the dowry. The dowry is a sum paid by the woman's family to the man, as this was seen as essential 'seed capital' that established a stable marriage, and also because women were often seen as such a useless burden that men would have to be incentivized to marry them.
