The Hellenistic period started when Alexander the Great entered Egypt in 332 BCE. After the death of Alexander in 323 BCE, Egypt was ruled by Ptolemy I, one of his army generals, then by Ptolemy’s descendants, for about 300 years. This period ended with the death of Cleopatra, the last Ptolemic queen, during 30 BCE. Cleopatra and Marcus Antonius were defeated by the Roman General Octavian who added Egypt to the Roman Empire. Egypt remained under the Roman rule until the Arab conquest in 641 CE. The largest collection in the Bibliotheca Alexandrina Antiquities Museum dates back to the Greco-Roman period. It reflects the Greek and Roman religious concepts, and part of it represents some aspects of the daily life.
