The oldest recorded words from any woman living in (what is today) Scotland are someone telling the empress of Rome, to her face, that they fuck better than her
Empress-consort rather than empress-regnant, I’m afraid. She was Julia Domna, wife of emperor Septimus Severus and accompanying him on his attempt to bring the north of Britain under his control
That said, there absolutely were empresses-regnant of the Byzantine empire, and there’s no reason to consider that a separate entity. Irene Sarantapechaena and about four or five others absolutely were ruling Roman empresses
I had to look that up, it’s just too good to pass.
(Cassius Dio, contemporary historian) tells us that the empress teased her companion (the wife of Argentocoxos, a Caledonian chief) by saying that Caledonian women indulge in a sexual free-for-all, sharing their beds with different men while making no attempt to conceal their adultery. To a respectable aristocratic lady like Julia, such brazen promiscuity would indeed have seemed worthy of comment. We then see the wife of Argentocoxos swiftly responding with what Dio calls ‘a witty remark’ of her own:
“We fulfil the demands of nature in a much better way than do you Roman women; for we consort openly with the best men, whereas you let yourselves be debauched in secret by the vilest.”
A bit further below, however
The consensus view among present-day historians is that he simply invented the speech quoted above.
