Sumer
Sumer () is the earliest known civilization in the historical region of southern Mesopotamia, modern-day southern Iraq, during the Chalcolithic and Early Bronze ages, and one of the first civilizations in the world along with Ancient Egypt and the Indus Valley. Living along the valleys of the Tigris and Euphrates, Sumerian farmers were able to grow an abundance of grain and other crops, the surplus of which enabled them to settle in one place. Prehistoric proto-writing dates back before 3000 BC. The earliest texts, from c. 3300 BC, come from the cities of Uruk and Jemdet Nasr; early cuneiform script emerged around 3000 BC.
Kernos
The form begins in the Neolithic in stone, in the earliest stages of the Minoan civilization, around 3,000 BC. They were produced in Minoan and Cycladic pottery, being the most elaborate shape in the latter, and right through ancient Greek pottery. The Duenos Inscription, one of the earliest known Old Latin texts, variously dated from the 7th to the 5th century BC, is inscribed round a "kernos" of three linked pots, of an Etruscan type.
