A 'marriage' mocked by Nero's peers. A seriously demented Caesar...<quoted text>
The first historical mention of the performance of same-sex marriages occurred during the early Roman Empire. For instance, Emperor Nero is reported to have engaged in a marriage ceremony with one of his male slaves. Emperor Elagabalus "married" a Carian slave named Hierocles. These were usually reported in a critical or satirical manner. It should be noted, however, that conubium existed only between a civis Romanus and a civis Romana (that is, between a male Roman citizen and a female Roman citizen), so that a marriage between two Roman males (or with a slave) would have no legal standing in Roman law (apart, presumably, from the arbitrary will of the emperor in the two aforementioned cases). Furthermore, "matrimonium is an institution involving a mother, mater. The idea implicit in the word is that a man takes a woman in marriage, in matrimonium ducere, so that he may have children by her." Still, the lack of legal validity notwithstanding, there is a consensus among modern historians that same-sex relationships existed in ancient Rome, but the exact frequency and nature of "same-sex unions" during that period is obscure. In 342 AD Christian emperors Constantius II and Constans issued a law in the Theodosian Code (C. Th. 9.7.3) prohibiting same-sex marriage in Rome and ordering execution for those so married.
A same-sex marriage between the two men Pedro Díaz and Muño Vandilaz in the Galician municipality of Rairiz de Veiga in Spain occurred on 16 April 1061. They were married by a priest at a small chapel. The historic documents about the church wedding were found at Monastery of San Salvador de Celanova.
A speculation that is countered by the attempted 'marriage' of two women in Spain. They were promptly corrected.
