Papyrus Bingen 45

Papyrus Bingen 45 (also known as Papyrus Berlin 25239 or the Cleopatra Papyrus) is a 1st-century BC manuscript in Koine Greek, which is now part of the Berlin Papyrus Collection and displayed in the Neues Museum, Berlin.

Being an official ordinance, it mainly grants certain tax exemptions for wine and wheat to a Roman citizen, whose identity is disputed; some scholars argue it is Publius Canidius Crassus, the commander of Mark Antony's land forces in the Battle of Actium (31 BC).

The papyrus is the last extant dated ordinance of a Ptolemaic monarch. It is well known because since 2000 some historians have argued that its concluding subscription "γινέσθωι" (ginésthōi; lit. 'so be it' or 'make it happen') is an autograph of Cleopatra, the last queen of the Ptolemaic Kingdom of Egypt. The papyrus would thus contain the only surviving autograph of a major figure from antiquity.

There exist, however, many points of ongoing scholarly contention regarding the papyrus – including the authorship of its concluding subscription.
