There is this, from the Talmud (Sanhedrin 19a) - bold is a translation from the original, non-bold is the interpolated explanation:
And Rami bar Abba says: Rabbi Yosei instituted an ordinance in Tzippori (Sepphoris, northern Israel) that women should converse in the bathroom, because of the restrictions on women being secluded with men. Since the public bathrooms there were outside the city a man might enter to take advantage of a woman, but he would be warded off by the womenβs conversation.
Rabbi Yosei lived in the mid-2nd century; Rami bar Abba, who reports this, lived about a century later.
