The first date in literature appears in the 5,000-year-old Sumerian Epic of Gilgamesh. In order to tame Enkidu, a Tarzan-like wild man who is terrorising his people, the king Gilgamesh sends Shamhat, a beautiful prostitute. There was no question of first date nerves. They meet at a waterhole where "Shamhat loosened her undergarments, and he took in her attractions".
