Here is an interesting record in Usher's The Annals of the World. (Master Books Edition): It concerns Cambyses, emperor of Persia, 524-523 BC:
Cambyses wanted to prepare a navy to go against the Carthaginians, but gave it up when the Sidonians, upon whom he relied for naval service, refused to go against their own colony and kindred. Meanwhile, he sent for some of the Fish Eaters from the city of Elephantine, who were well versed in the Ethiopian language. He sent them as spies to the Ethiopians, who were known as the Long Lived. These are a generally very long-lived people who dwell in the parts of Africa south of Egypt. . .The spies went under the pretence of bearing gifts for their king. . .In their presence, the king of Ethiopia took his bow and bent it, and then straightened it again. He handed it to them to carry to Cambyses, and asked them to tell him that when his Persians were able to bend such bows as these with ease, then and not before, would he be able to gather a large army and fight against the long-lived Ethiopians.
Cambyses' full brother, Smerdis or Tanyoxarces, tried to bend this bow and came within two fingers' breadth of the notch, but none of the other Persians came that close. Out of envy, Cambyses dismissed him and sent him to Persia.
In a rage, Cambyses ordered an expedition against Ethiopia, without making any provisions for grain or food. Like a mad man, as soon as he had heard what his Fish Eaters has said, he immediately marched off with all his own foot soldiers, ordering the Greeks to stay behind.
When he came as far as Thebes in Egypt, he selected about fifty thousand of his army and sent them to rob the land first, and then to burn the temple of Jupiter Ammon, making slaves of all the inhabitants of the place as they did so. Then he marched on toward Ethiopia. . . .
The army, which set out from Thebes against the Ammonians, travelled seven days across the sands before coming to the city of Oasis. . . .As they marched from there across the sandy plains and were midway between Oasis and Ammonia, it is said that while they were eating, a very strong wind arose out of the south. It brought those shifting sands upon them and overwhelmed them all. Fifty thousand men died in the sand storm.
The army which was going with him against the Ethiopians ran out of provisions after five days. When they had lost hope of any food, they cast lots and started to eat one another. When Cambyses saw this, he returned to Thebes, having lost most of his army. . . .
When Cambyses returned to Memphis, he discharged his Greeks and shipped them home. He saw the Egyptians keeping a holy day because their god Apis had appeared to them. Apis was a sacred bull worshipped in the temple of Ptah in Memphis. Cambyses thought they had celebrated for joy at his disastrous journey. He sent for Apis and killed the animal with his sword. He commanded all his priests to be scourged with whips, and the rest of the Egyptians who were found keeping the holy day were to be killed by his soldiers. . . .
The Egyptians said the Cambyses, who was mentally unstable, now went stark raving mad. This first manifested itself when he killed his own brother. After he had sent him to Persia (as was said before), Cambyses dreamed that a messenger arrived from there to tell him that Smerdis, his brother, was sitting on the regal throne and touching the heavens with his head. He was astonished by this dream and immediately sent Prexaspes, his most trusted friend, to kill his brother Smerdis. When he came to Susa, he had him murdered. Some say he took him on a hunting trip, others report that he lured him along as far as the Persian Gulf and drowned him in it. . . .
When Cambyses saw his wife Meroe grieving for her brother Smerdis, he killed her too. . . .
Cambyses killed Prexaspes' son, who was his cup bearer, with an arrow. The next day he had twelve principal men of the Persians buried alive with their heads downward, though they had done him no harm. He ordered that Croesus, who had for some time been king of Lydia, be executed because he had admonished him, in a fair and friendly manner, not to do such things. He changed his mind before the execution, but killed those whom he had appointed to kill Croesus. He played many similar mad pranks on the Persians and on his friends while he stayed at Memphis. He opened many of their sepulchres to see the bodies of those who lay buried there. He went into the temple of Vulcan, where he laughed exceedingly and mocked his image. Another time he went into the temple of the Cabeiri, where only the priests were to go. After jeering their images, he had them all burned. He either burned down, pulled down, defaced or destroyed the remainder of their temples and did the same to their obelisks.
