Question: The Dio of Alexandria was sent to complain about which Egyptian king of Macedonian decent?

 He was sent by his fellow-citizens as ambassador to Rome, to complain about the conduct of their king, Ptolemy XII Auletes.  On his arrival at Rome he was poisoned by the king's secret agents, and the strongest suspicion of the murder fell upon Marcus Caelius. Dio of Alexandria (Greek: Δίων ) was an Academic philosopher and a friend of Antiochus of Ascalon who lived in the first century BC.  The defence of Caelius in April 56 BC, the "Pro Caelio", is considered one of Cicero's and indeed Rome's greatest orations. <SEP> Diopeithes (in Greek Διoπείθης; lived during the 4th century BC) was an Athenian general, probably father of the poet Menander, who was sent out to the Thracian Chersonese about 343 BC, at the head of a body of Athenian settlers or κληρoυχoι.  Disputes having arisen about their boundaries between these settlers and the Cardians, the latter were supported, but not with arms in the first instance, by king Philip II of Macedon (359-336 BC), who, when the Athenians remonstrated, proposed that their quarrel with Cardia should be referred to arbitration.  This proposal being indignantly rejected, Philip sent troops to the assistance of the Cardians, and Diopeithes retaliated by ravaging the maritime district of Thrace, which was subject to the Macedonians, while Philip was absent in the interior of the same country on his expedition against Teres and Cersobleptes.  Philip sent a letter of remonstrance to Athens, and Diopeithes was arraigned by the Macedonian party, not only for his aggression on the king's territory, but also for the means to which he resorted for the support of his mercenaries.  He was defended by Demosthenes in the oration, still extant, "On the Chersonese", 341 BC, and the defence was successful, for he was permitted to retain his command.  After this, and probably during the war of Philip with Byzantium (340 BC), Diopeithes again invaded the Macedonian territory in Thrace, took the towns of Crobyle and Tiristasis and enslaved the inhabitants, and when an ambassador, named Amphilochus, came to negotiate for the release of the prisoners, he seized his person in defiance of all international law, and compelled him to pay nine talents for his ransom.  The enmity of Diopeithes to Philip appears to have recommended him to the favour of the king of Persia Artaxerxes III, who, as we learn from Aristotle, sent him some valuable presents, which arrived just prior to his death. <SEP>  Auletes means "pipes-player", referring to the king's love of playing the pipes. Ptolemy Neos Dionysos Theos Philopator Theos Philadelphos (117–51 BC; Ancient Greek: Πτολεμαῖος Νέος Διόνυσος Θεός Φιλοπάτωρ Θεός Φιλάδελφος , spoken "Ptolemaios Néos Diónysos Theós Philopátōr Theós Philádelphos" ≈ Ptolemy New Dionysus, God Beloved of his Father, God Beloved of his Brother), more commonly known as "Auletes" (Αὐλητής , "Aulētḗs" = the Flutist) or "Nothos" (Νόθος , "Nóthos" = the Bastard), was an Egyptian king of Macedonian descent. <SEP> Amasis was a Persian of the tribe of the Maraphii, who was sent by Aryandes, the governor of Egypt under Cambyses, at the head of an army to assist Pheretima, the mother of Arcesilaus III, king of Cyrene.  In one of his works, philologist Edward Pococke associates the Maraphii with the Berhi-pae of Kartakeyu.  He took Barca by stratagem and treachery, and made an unsuccessful attempt upon Cyrene.  He was then recalled by Aryandes.  On its march back the Persian army suffered severely from the Libyans and a little later it is claimed they appointed the soon to be Egyptian king Amasis II as their leader.
