Mardonius

Mardonius's importance began with his blood. His father Gobryas (Old Persian Gaubaruva) was one of the six who joined Darius in the coup of 522, and stands among the spear-bearers on the Behistun relief; Darius names him in the great inscription, "(one) called Gaubaruva, son of Marduniya, a Persian," among the men "who strove as my followers" when he killed Gaumata.^[1] The grandfather, then, was another Mardonius, so the general carries the name of the coup-maker's own father. Gobryas married a sister of Darius, and Mardonius was the son of that marriage; Darius in turn gave Mardonius one of his daughters, named by Herodotus as Artozostre. Herodotus records the marriage plainly at the head of the 492 campaign, calling him "a man young in years and lately wedded to Darius' daughter Artozostre".^[2]

That union is one of the rare points where the Greek record and the empire's own paperwork touch. A Persepolis Fortification tablet, PFa 5, records rations for a woman described as "the wife of Mardonius, daughter of the king" (Elamite Mardunuya irtiri sunki pakri), an unnamed royal princess, in all likelihood Artozostre herself.^[3] Mardonius appears again by name in the glossary of the Fortification archive, and a cluster of later Babylonian contracts records an estate still worked under his name. The man Herodotus dramatises was, on the ground, a documented great landholder of the realm, not merely a character in a Greek war-story.^[4]

The position this gave him was formidable but, it should be said, hardly singular. As one of Darius's chosen sons-in-law he stood in the innermost circle of the reign; under Xerxes, as royal cousin and brother-in-law, he was one grandee among several of comparable rank, a point that bears on the Greek claim that he alone drove the King to war.^[5] His father's generation had made the dynasty; his own task was to serve it in the field.

Mardonius first commands in the sources in 492, when Darius, the Ionian Revolt freshly suppressed, sent him west with a large army and fleet. Herodotus casts the expedition as aimed at punishing Athens and Eretria for their share in the burning of Sardis, and calls it a failure; its real work, and its real result, was the reassertion of imperial control over the European foothold, Thrace and Macedonia, that the revolt had shaken. Herodotus's own narrative shows this, for the campaign's memorable disaster is a shipwreck, not a battle lost:

Crossing then over from Thasos they voyaged near the land as far as Acanthus, and putting out from thence they would have rounded Athos. But as they sailed, there brake upon them a north wind great and irresistible, and dealt very roughly with them, driving many of their ships upon Athos; three hundred, it is said, was the tale of the ships that perished, and more than twenty thousand men.

Herodotus 6.44, trans. Godley^[2]

The fleet's disaster at Athos became a byword, and it is the reason Xerxes' engineers would later cut a canal through the Athos peninsula rather than risk the passage again. On land Mardonius was mauled too, wounded in a night attack by the Thracian Brygi, but he would not withdraw until he had subdued them:

Thus then it fared with the fleet; as for Mardonius and his land army, while they were encamped in Macedonia the Brygi of Thrace attacked them by night, and slew many of them, wounding Mardonius himself. Nevertheless not even these themselves could escape being enslaved by the Persians; for Mardonius did not depart out of those lands before he had made them subject to him.

Herodotus 6.45, trans. Godley^[2]

Herodotus's verdict, that the expedition "after an inglorious adventure returned back to Asia," reflects his framing of the campaign as a botched strike at Athens.^[2] Schmitt's reference article stays close to that framing, calling the campaign "almost a total failure" that nonetheless consolidated Persian rule in Thrace and Macedonia.^[6] The fuller reassessment belongs to the Companion and to Kuhrt, who set the failure-verdict aside and read the campaign as a successful frontier-restoration. On the Companion's account the punitive aim is Herodotus's, and the Persians' "real intention was presumably to reestablish their control over Thrace and Macedon", a reconquest the revolt had interrupted;^[4] Kuhrt concurs that "Mardonius' subsequent action makes it plain that his aim was to consolidate Persian power in Thrace and adjoining regions."^[7] On this reading the storm at Athos and the wound from the Brygi were the real costs of a campaign that achieved its strategic purpose; the "failure" is Herodotus's, imposed by treating a punitive raid on Athens as the goal.

One notice from the 492 campaign has drawn more comment than the shipwreck. Passing through Ionia on his way to the Hellespont, Mardonius put down the tyrants the Persians had installed in the Greek cities of Asia and replaced them with popular governments, and Herodotus flags the report as something his Greek readers will scarcely credit:

When Mardonius arrived at Ionia in his voyage by the coast of Asia, he did a thing which I here set down for the wonder of those Greeks who will not believe Otanes to have declared his opinion among the Seven that democracy was best for Persia: Mardonius deposed all the Ionian despots and set up democracies in their cities.

Herodotus 6.43, trans. Godley^[2]

The aside points back to the "Constitutional Debate" Herodotus had staged among the conspirators, where Otanes argues for popular rule (see the accession of Darius); the surprise, for a Greek, is a Persian grandee sponsoring dēmokratiai at all. The historicity of a sweeping conversion to democracy has long been doubted, and the modern reading treats the measure not as a Persian experiment in constitutional theory but as pragmatic frontier management. On the Companion's account the empire was simply indifferent to the constitutional form of its subjects: "when the Persians thought that democratic rule was more beneficial for their goals they did not hesitate to remove tyrants and to install democracies in Ionian states", the choice of despotism or democracy playing no part in the calculation.^[4] What Mardonius did in Ionia, on this view, was to decline to reimpose the unpopular tyrant-clients whose rule had helped provoke the revolt, and to settle the province on terms its cities could live with. The measure fits the campaign's real character as a work of consolidation rather than punishment, and it shows Mardonius, at the very start of his career, handling a delicate political settlement and not merely marching an army.

When Darius died in 486 the reckoning with Greece passed to Xerxes, and here Mardonius enters the record in his most famous and most suspect role: the man who talks the King into the great invasion. Herodotus makes him the standing voice at Xerxes' side, the cousin who "was ever with the king and had more influence with him than any Persian",^[8] and gives him the speech that urges vengeance on Athens once Egypt is subdued:

Sire, it is not seemly that the Athenians should go unpunished for their deeds, after all the evil they have done to the Persians. Nay, my counsel is that for the nonce you do what you have in hand; then, when you have tamed the insolence of Egypt, lead your armies against Athens, that you may have fair fame among men.

Herodotus 7.5, trans. Godley^[8]

To the argument from vengeance Herodotus adds the lure of a rich Europe "worthy of no mortal master but the king", and then supplies the motive behind the motives, the charge that fixed Mardonius's character for antiquity: "This he said, because he desired adventures, and would himself be viceroy of Hellas."^[8] In the war-council that follows, Mardonius alone speaks for the expedition and belittles the Greeks, while the wise elder Artabanus (Xerxes' uncle) counsels caution and is abused for it; then a dream overrides the King's better judgement.

The scene is vivid, but its evidential value is slight, and the grounds for doubt are concrete. Briant identifies the whole set-piece as a literary construction working post eventum: "It was standard practice to contrast two counselors, one ambitious and stupid, the other wise and deliberate," a pairing whose "result, if not the intention," is to portray Xerxes as weak, "which fits well with the traditional Greek presentation."^[9] Mardonius, cast as the ambitious fool, may indeed have had a poor name among the Persians themselves; but that is a fact about his later reputation rather than proof that the invasion was his doing.^[9] John Hyland presses the point to its root: Herodotus "inadvertently reproduces a trope of apologetic royal ideology in the stock character of an evil adviser, whose deceptive counsel exempts the king from blame," a device visible in the very structure of the story, since after yielding to Mardonius the King is still free to change his mind, until a supernatural dream forces his hand.^[5] The specific detail that Mardonius wished to become "viceroy of Hellas"^[8] Hyland judges an inference read back from his later command and "implausible as the ambition of an Achaemenid courtier whose wealth and family power were rooted in the Persian heartland": a man whose estates lay in Persis and Babylonia had little reason to crave a satrapy at the far edge of the world, still less to send the King in person to win it for him.^[5]

The cause of the invasion, on the modern reading, lies in the office of kingship rather than the whisper of a favourite. Xerxes' choice to lead a royal campaign in person, after suppressing the revolts of Egypt and Babylon that had greeted his accession, was a demonstration of effective kingship, a bid to match and exceed the marches of Cyrus and Darius and to renew in person the bonds of loyalty across the empire.^[5] Briant agrees that "for Xerxes the situation was very clear": he had to take up his father's unfinished plan, prove his ability to lead a victorious campaign, and show himself to his subject peoples along the way; the decision was structural rather than the product of one man's ambition.^[9] Mardonius no doubt spoke for the war and helped plan the infrastructure in the region of his old command, but he "would not have been the only noble enthusiastic for the royal campaign."^[5] The war-hawk of Book 7 is, in large part, a figure the defeat required.

Whatever the truth of the council, Mardonius's actual place in the invasion of 480 is not in doubt: he was one of the senior commanders of the largest army the empire ever put in the field. Herodotus lists him first among the marshals who led the host out of Sardis, and gives him, with Masistes, command of one of the three great columns of the march through Thrace.^[7] He was, in the Iranica article's phrase, Xerxes' "commander-in-chief" in the sense of the leading field officer under the King himself.^[6] Through the campaign of that summer, the forcing of Thermopylae, the drawn sea-fights off Artemisium, the occupation of Attica and the burning of the Athenian Acropolis, he is one of the men directing the war (see the invasion of Greece), though Herodotus, whose interest is in the King and in the Greek defenders, gives him few distinct scenes until the crisis after Salamis.

That crisis came at sea. Drawn into the narrows of Salamis in September 480, the empire's subject fleet was beaten while Xerxes watched from the shore. The blow to the royal image was heavy, but the army itself came through largely intact, and what followed was not the panicked flight of the Greek sources but a considered division of force, of which Mardonius was both author and instrument.^[10] Herodotus gives him the speech in which he offers to stay behind and finish the war, absolving the Persians of the naval disaster and asking for a picked army:

Do not, O king, make the Persians a laughing-stock to the Greeks; for if you have suffered harm, it is by no fault of the Persians, nor can you say that we have anywhere done less than brave men should; and if Phoenicians and Egyptians and Cyprians and Cilicians have so done, it is not the Persians who have any part in this disaster. Wherefore since the Persians are nowise to blame, be guided by me; if you are resolved that you will not remain, do you march away homewards with the greater part of your army; but it is for me to enslave and deliver Hellas to you, with three hundred thousand of your host whom I will choose.

Herodotus 8.100, trans. Godley^[11]

The speech is Herodotus's composition, but the strategy it frames is sound and was the one adopted: Xerxes withdrew to Sardis with the fleet and from there "was in constant communication with Mardonius, and he continued to oversee the entire operation," while Mardonius held the army in Greece to force a decision on land.^[10] To leave a subordinate to complete a war the King had opened was ordinary Achaemenid practice, and a victory won that way would have redounded to Xerxes' own credit, as his father's generals' victories had.^[12] The arrangement held the Greek fleet in its home waters and forced the war's decision onto Greek soil.^[10] The retreat was a plan, and Mardonius held its sharp end.

Mardonius wintered his picked force in Thessaly and, in the spring of 479, opened not with a march but with an offer. Through Alexander I of Macedon, the King's Macedonian client and a guest-friend of Athens, he carried Xerxes' peace terms to Athens. As Alexander delivered them, they were strikingly generous:

There is a message come to me from the king, saying, 'I forgive the Athenians all the offences which they have committed against me; and now, Mardonius, I bid you do this:—Give them back their territory, and let them choose more for themselves besides, wheresoever they will, and dwell under their own laws; and rebuild all their temples.'

Herodotus 8.140, spoken to Athens by Alexander of Macedon, trans. Godley^[13]

The overture was strategy, not weakness. Hyland reads it as a calculated wedge, meant to divide Athenian hardliners from any party of compromise and to loosen Athens from Sparta, with the option of renewed force held in reserve if the city refused.^[12] The reconquest of Athens that followed was, in Hyland's reading, a required objective rather than the vanity Herodotus alleges, since the city's earlier submission made its renewed resistance a rebellion demanding the reassertion of royal authority.^[12] Mardonius advanced into Attica, retook and razed the evacuated city, and from it sent the offer a second time, through a Hellespontine envoy named Murychides, reasoning that with Attica "the captive of his spear" the Athenians, refugees on Salamis, might soften.^[13] When Murychides put the terms to the council on Salamis, one councillor, Lycidas, proposed only that the offer be laid before the people; the councillors and the crowd stoned him to death, and the Athenian women, "one calling to another", went to his house and stoned his wife and children.^[13] The response was unanimous rejection. Athens held, and appealed again to Sparta.

His diplomacy spent, Mardonius fell back from Attica to fight where his strengths told. He chose the plain of the Asopos in Boeotia, near friendly Thebes: "Attica is not cavalry country", Herodotus has him reason, and Boeotia gave his horse room to work.^[7] That arm was his advantage, and his handling of it has drawn a sharp reassessment of the man as a soldier. Where Herodotus and the older tradition saw a general blundering toward his doom, Hyland finds careful method: through the standoff before the battle Mardonius used his cavalry to foul the enemy's water and cut its supply line, and gave battle only when a night withdrawal left the allied army split, sleepless and short of water. On the eve of the fighting, in Hyland's judgement, "Mardonios's cavalry was on the verge of winning the campaign."^[12] The engagement itself, the cavalry actions and the death of the commander Masistius that first lifted Greek morale, belongs to the battle (see Plataea).^[14]

The battle turned on Mardonius himself. When the Persian infantry met the Spartans, Herodotus says, they held their ground so long as he was alive and in the fight, conspicuous on a white horse among his picked thousand:

Where Mardonius was himself, riding a white horse in the battle and surrounded by a thousand picked men who were the flower of the Persians, there they pressed their adversaries hardest. So long as Mardonius was alive the Persians stood their ground and defended themselves, overthrowing many Lacedaemonians; but when Mardonius was slain and his guards, who were the strongest part of the army, fallen likewise, then the rest too yielded and gave ground before the men of Lacedaemon.

Herodotus 9.63, trans. Godley^[14]

He was killed by a Spartan whom Herodotus names Aeimnestus, and the Greeks read the death as the settling of an old score: the Spartans "gained from Mardonius their full measure of vengeance for the slaying of Leonidas, according to the oracle".^[14] The manner of the death fixed the man's memory as much as the defeat did. A great noble was expected to lead from the front, and the display his rank demanded, the white horse, the forward station, made him the one target whose fall could break the army; by the reckoning of his own class it signalled divine favour withdrawn.^[15] Hyland's reconstruction turns the outcome away from any inferiority of the Persian soldier and toward the accidents of the day, the congested advance and the commander's chance death, so that the defeat need not have followed from the campaign Mardonius had all but won.^[15] With him died the bid to add Greece to the empire, and with it a reputation the winners' account would carry down: the reckless favourite who dragged an army to ruin and paid for it.

Mardonius furnishes one of the neatest small puzzles in Achaemenid source-criticism, and it turns on the one kind of evidence the Greek narrative lacks: a Babylonian business document. A handful of cuneiform contracts, associated with a brickmakers' workshop, record large orders placed by one Kî-Bēl, named as the household steward of a grandee called Mardonius; two of them are dated to the eighth regnal year of Xerxes, that is, to about a year after the general's death at Plataea.^[16] The difficulty is plain: a dead man's estate appears to be still transacting business under his name. Three answers have been given, and they map the whole spectrum of how this evidence can be read. Matthew Stolper, who first published the texts, offered two: either they name a different, homonymous Persian grandee, or they involve the household of the famous Mardonius as "a posthumous mention of a man whose prerogatives and property had not been re-assigned or whose agent had not yet found a new affiliation."^[17][16] Kuhrt takes the first, cautious line, judging the owner "unlikely to be identical with the Herodotean Mardonius, as the text dates after Mardonius' death at Plataea."^[7] A third and bolder reading has been floated: that the estate did belong to the general, and that he therefore did not die at Plataea at all, the Greek account of his death being fiction. The Companion airs this possibility, that the death-notice may not be secure:

Even the report on the death of Mardonius in the battle of Plataea might be ficticious [sic] if the noble Mardonius mentioned some years later in a Babylonian document by referring to his far-reaching estates is the general of the Persian Wars.

A Companion to the Achaemenid Persian Empire (2021), p. 435^[4]

The bold reading does not survive scrutiny, and Hyland sets it aside decisively. To suppose Mardonius survived Plataea "would violate a strong source tradition and cause further problems of reconstruction," for it would require the Greek sources to have invented the death together with everything the record attaches to it: the competition over his corpse and belongings, the reward his son Artontes offered to the man who claimed to have buried him, and the immediate succession of Artabazus to the command.^[16] Stolper's own prosaic explanation makes the fiction unnecessary: the survey and reassignment of a dead grandee's assets, and the sorting of crown grants from private property, was "a slow and laborious process," and in the interval local agents would have gone on cultivating the estate under their old master's title while they waited for the King to resolve its ownership.^[16] A great man's death did not instantly erase his name from the ledgers of his stewards. Handled carefully, the anomaly does not overturn the battle. It shows instead how much can be built on a single documentary oddity, and why the weight of the tradition, set against the ordinary slowness of settling a dead grandee's estate, holds against the bolder reading.

Mardonius is the tradition's clearest case of a historical person all but replaced by a literary function. Herodotus needed a hawk to drive the war and a villain to bear its defeat, and Mardonius, royal kinsman, chief advocate, field commander, and the man who actually died on the losing field, fitted the part at every point; so the ambitious counsellor who rejects wise advice and forces a needless battle took shape and held the Western imagination. That afterlife has proved the durable thing about him: the Mardonius who reaches the modern reader is still largely Herodotus's, the reckless favourite of the war-council and the doomed general of Book 9, and the corrective the Persian and documentary evidence supports has barely dented the legend. Herodotus's charge that he "desired adventures"^[8] glosses a commander's ordinary willingness to give battle; the craving for a Greek satrapy is an inference from his last command; and the villain's death let a lost war find its scapegoat, a portrait Hyland argues "may be rooted in scapegoating due to his eventual failure".^[5] The correction is not that Mardonius was blameless or brilliant, matters on which the evidence is silent, but that the confident Greek portrait rests on a narrative built to make the Persian defeat a moral lesson, and cannot be trusted as a likeness. Between the war-hawk of legend and the son of Gobryas attested in a Persepolis tablet and a Babylonian ledger stands a real commander whom the winners' sources show only in outline.
