Now none of the fragments we have mention that they are the opening of any book nor the ending, where has this claim come from? The author believes that Kleitarchos assigned one year of the reign to an individual book, Diodoros too writes annalistically so presumably his method is to look at where Diodoros places his year divisions in Book XVII. Not a ridiculous notion, an author like Diodoros may well have preserved the book endings and beginnings as convenient yearly divisions. But just how true is this assumption?
2 1 When Evaenetus was archon at Athens, the Romans elected as consuls Lucius Furius and Gaius Manius.2 In this year Alexander, succeeding to the throne, first inflicted due punishment on his father's murderers,3 and then devoted himself to the funeral of his father. 2 He established his authority far more firmly than any did in fact suppose possible, for he was quite young and for this reason not uniformly respected, but first he promptly won over the Macedonians to his support by tactful statements.4 He declared that the king was changed only in name and that the state would be run on principles no less effective than those of his father's administration. Then he addressed himself to the embassies which were p123present and in affable fashion bade the Greeks maintain towards him the loyalty which they had shown to his father. 3 He busied his soldiers with constant training in the use of their weapons and with tactical exercises, and established discipline in the army.
This is all well and good as a start to an Alexander history but now we come to our first reason to doubt the next year notice is
This is TWO years on, the previous year had ended with the banquet/festival just before the crossing and this book starts with the crossing itself. Is it likely that this occured on the same day as the battle of Gaugamela? Arrian tells us that Alexander crossed twenty days after the beginning of the campaigning season (I xi) which certainly did not start in September. Already the annalistic Kleitarchos is confounded. Book I consisted of two years and ended not with the Olympian Games at Aigai as established by Archelaos and celebrated by Philip after the fall of Olynthos, the date of the Festival is, unfortunately, unclear, but with the later celebrations described by Chares but not dated. Book two would begin at least twenty days later probably a whole season.17 1 When Ctesicles was archon at Athens, the Romans elected as consuls Gaius Sulpicius and Lucius Papirius. Alexander advanced with his army to the Hellespont and transported it from Europe to Asia. 2 He personally sailed with sixty fighting ships to the Troad, where he flung his spear from the ship and fixed it in the ground, and then leapt ashore himself the first of the Macedonians, signifying that he received Asia from the gods as a spear-won prize. 3 He visited the tombs of the heroes Achilles, Ajax, and the rest and honoured them with offerings and other appropriate marks of respect, and then proceeded to make an accurate count of his accompanying forces.
It ends with ‘the capture of the littoral as far as Cilicia’ an event that belongs after the move from Gordion in 333 once again not synchronous with the other book endings. Then we have
A retrospective report of the Persian side of things bringing matter back into synch; Alexander heard of Memnon’s death once he reached Tarsos in Cilicia. The rest of the book concerns the campaign of Issos ending with the evening of the battle since the next division starts29 1 When Nicocrates was archon at Athens, Caeso Valerius and Lucius Papirius became consuls at Rome. In this year Dareius sent money to Memnon and appointed him commanding general of the whole war. 2 He gathered a force of mercenaries, manned three hundred ships, and pursued conflict vigorously. He secured Chios, and then coasting along to Lesbos easily mastered Antissa and Methymna and Pyrrha and Eressus. Mitylenê also, large and possessd of rich stores of supplies as well as plenty of fighting men, he nevertheless captured with difficulty by assault after a siege of many days and with the loss of many of his soldiers. 3 News of the general's activity spread like wildfire and most of the Cyclades sent missions to him. As word came to Greece that Memnon was about to sail to Euboea with his fleet, the cities of that island became alarmed, while those Greeks who were friendly to Persia, notably Sparta, began to have high hopes of a change in the political situation. 4 Memnon distributed bribes freely and won many Greeks over to share the Persian hopes, but Fortune nevertheless put an end to his career. He fell ill and died, seized by a desperate malady, and with his death Dareius's fortunes also collapsed
This division is day specific, it is the day after the battle as we shall she the very same construct is used for Gaugamela, yet they were fought in different months. Once again, no synchronism.40 1 When Niceratus was archon at Athens, the Romans elected as consuls Marcus Atilius and Marcus Valerius, and the one hundred and twelfth Olympic Games were held, in which Grylus of Chalcis was the victor. In this year, Alexander buried the dead from his victory at Issus, including even those of the Persians who had distinguished themselves by courage. Then he performed rich sacrifices to the gods and rewarded those who had borne themselves well in battle with gifts appropriate to each, and rested the army for some days. 2 Then he marched on towards Egypt, and as he came into Phoenicia, received the submission of all the other cities, for their inhabitants accepted him willingly.
The next division comes at the capture Gaza.
49 1 In the archonship of Aristophanes at Athens, the consuls at Rome were Spurius Postumius and Titus Veturius. In this year King Alexander set in order the affairs of Gaza and sent off Amyntas with ten ships to Macedonia, with orders to enlist the young men who were fit for military service. He himself with all his army marched on to Egypt and secured the adhesion of all its cities without striking a blow. 2 For since the Persians had committed impieties against the temples and had governed harshly, the Egyptians welcomed the Macedonians.
Then we have a division at at the end of the battle of Gaugamela or Arbela in Diodoros
And and then62 1 When Aristophon was archon at Athens, the consular office at Rome was assumed by Gaius Domitius and Aulus Cornelius. In this year word was brought to Greece about the battle near Arbela, and many of the cities became alarmed at the growth of Macedonian power and decided that they should strike for their freedom while the Persian cause was still alive. 2 They expected that Dareius would help them and send them much money so that they could gather great armies of mercenaries, while Alexander would not be able to divide his forces. 3 If, on the other hand, they watched idly while the Persians were utterly defeated, the Greeks would be isolated and never again be able to think of recovering their freedom.
64 1 After his defeat in the battle near Arbela, Dareius directed his course to the upper satrapies, seeking by putting distance between himself and Alexander to gain a respite and time enough to organize an army. He made his way first to Ecbatana in Media and paused there, picking up the stragglers p301from the battle and rearming those who had lost their weapons.1 2 He sent around to the neighbouring tribes demanding soldiers, and he posted couriers to the satraps and generals in Bactria and the upper satrapies, calling upon them to preserve their loyalty to him.
3 After the battle, Alexander buried his dead and entered Arbela, finding there abundant stores of food, no little barbaric dress and treasure, and three thousand talents of silver.3 Judging that the air of the region would be polluted by the multitude of unburied corpses, he continued his advance immediately and arrived with his whole army at Babylon. 4 Here the people received him gladly, and furnishing them billets feasted the Macedonians lavishly.5 Alexander refreshed his army from its private labours and remained more than thirty days in the city because food was plentiful and the population friendly.
So what we can say is that if the year breaks in Diodoros do reflect the book breaks in Kleitarchos then his method was not annalistic but dramatic, he ended each book with bang, a revel, the story of the Mamares’ suicide rather than the chronological advent to Cilicia, the battle of Issos, the fall of Gaza, the battle of Gaugamela. There is simply no anniversarial ordering all of these events occured on different days and most likely different months.
