  Following the unification of the city-states in Assyria and Sumer by Sargon of Akkad into a single empire c. 2334 BC, a common Mesopotamian standard for length, area, volume, weight, and time used by artisan guilds in each city was promulgated by Naram-Sin of Akkad (c. 2254 –2218 BC), Sargon's grandson, including for shekels. Codex Hammurabi Law 234 (c. 1755–1750 BC) stipulated a 2-shekel prevailing wage for each 60-gur (300- bushel) vessel constructed in an employment contract between a shipbuilder and a ship-owner. Law 275 stipulated a ferry rate of 3- gerah per day on a charterparty between a ship charterer and a shipmaster. Law 276 stipulated a 2 1 ⁄ 2 -gerah per day freight rate on a contract of affreightment between a charterer and shipmaster, while Law 277 stipulated a 1 ⁄ 6 -shekel per day freight rate for a 60-gur vessel. In 1816, an archaeological excavation in Minya, Egypt (under an Eyalet of the Ottoman Empire) produced a Nerva–Antonine dynasty -era tablet from the ruins of the Temple of Antinous in Antinoöpolis, that prescribed the rules and membership dues of a burial society collegium established in Lanuvium, in approximately 133 AD during the reign of Hadrian (117–138) of the Roman Empire.
  
  A collegium was any association in ancient Rome that acted as a legal entity. Following the passage of the Lex Julia during the reign of Julius Caesar (49–44 BC), and their reaffirmation during the reign of Caesar Augustus (27 BC–14 AD), collegia required the approval of the Roman Senate or the Roman emperor in order to be authorized as legal bodies. Ruins at Lambaesis date the formation of burial societies among Roman Army soldiers and Roman Navy mariners to the reign of Septimius Severus (193–211) in 198 AD. In September 2011, archaeological investigations done at the site of the artificial harbor Portus in Rome revealed inscriptions in a shipyard constructed during the reign of Trajan (98–117) indicating the existence of a shipbuilders guild. Rome's La Ostia port was home to a guildhall for a corpus naviculariorum, a collegium of merchant mariners. Collegium also included fraternities of Roman priests overseeing ritual sacrifices, practising augury, keeping scriptures, arranging festivals, and maintaining specific religious cults.
