Did the Trusted Ptolemy Murder Alexander the Great? http://bit.ly/1WzXCeJ 

Alexander the Great was the ruler of one of the biggest empires in the ancient world. However, he died before his 33rd birthday, leaving behind a legend. He was careful and apparently avoided many assassination attempts during his life. Who could possibly be the person who murdered him? Was it Ptolemy, a man who had gained Alexander’s trust?

Family Ties

Ptolemy I Soter was born in 367 BC. He was perhaps the half-brother of Alexander and son of Philip II of Macedon with the beautiful Arsinoe. To avoid problems, Philip may have arranged the marriage of Arsinoe with a Macedonian nobleman named Lagus.

Regardless of a certain familial link, Philip treated Ptolemy as his own son. He took him to the capital at a young age and gave him as good of an education as he offered Alexander. Ptolemy was also sent to the school of Aristotle, where he was considered a talented student. It is unlikely that Philip would have invested so much attention and invited him to live in his palace, if Ptolemy had not been his child.
