Origins, Nature, and Names
Mandos belongs to the Ainur, those spirits brought forth from the thought of Ilúvatar before the making of the World, who sang in the Great Music and afterwards entered into Eä to give it shape. Among that company he is counted a Vala, and further among the eight named Aratar, the high ones whose might within Arda exceeds that of all others save Melkor, who is no longer reckoned in their number. He is thus a being without birth in any ordinary sense, of an order older than Elves and Men alike, and the Silmarillion assigns him no origin beyond that first coming into being. His station among the Valar is defined less by dominion over any region of the earth than by office: he is the one who declares judgment, and he does so only when Manwë has bidden him speak.
His proper name is Námo, a Quenya form built on a root meaning to judge or to ordain, so that the name itself amounts to a title of his office. That name, however, is rarely used. He is commonly called after the place where he abides — Mandos being properly the name of the halls in the west of Valinor, and only by transference the name of their master. Together with his brother Irmo, who is likewise better known by the name of his dwelling, Lórien, he forms a pair called the Fëanturi, the masters of spirits; Nienna is reckoned their sister. In the tongues of the Elves he is also the Doomsman of the Valar, a designation that renders his function rather than any personal quality.
Of his nature little is described beyond what suits that office. The Valaquenta says: “He forgets nothing; and he knows all things that shall be, save only those that lie still in the freedom of Ilúvatar.” He does not disclose such knowledge unbidden. His spouse is Vairë, called the Weaver, whose woven histories hold the deeds of time and hang within his halls, so that the record and the judgment are kept in the same house.
History
The first deeds recorded of Mandos belong to the long ages before the Sun, while the Valar still contended with Melkor for the ordering of Arda. After the Battle of the Powers, when Tulkas overthrew Melkor and bound him, the rebel Vala was brought captive to Aman and sentenced to confinement within the halls of Mandos, where he remained for three ages before he was permitted to sue for pardon. In the debate that followed the finding of the newly awakened Elves, the Valar were divided over whether the Quendi should be summoned westward, Ulmo holding that they were better left in the lands of their waking; the argument was closed when Mandos, who seldom spoke unbidden, declared the matter already appointed. That single word settled the policy from which nearly all the later griefs of the Noldor descended, and it is the earliest instance the histories give of his particular manner: brief, unarguable, and offered only once.
During the Years of the Trees his halls received their first Elvish inhabitant from among the dwellers in Aman. Míriel Serindë, spent by the bearing of Fëanor, laid down her body in the gardens of Lórien and would not take it up again, and her spirit passed westward to Mandos; Finwë's grief at her refusal, and his second marriage to Indis, set in motion the estrangement of Fëanor from his half-brothers. In the same period Mandos performed his office in its plainest form. When Fëanor drew sword upon Fingolfin in Tirion, the Valar summoned him to the Ring of Doom, and there Mandos delivered the sentence: banishment from the city for twelve years, with the warning that the deed would not be undone by the passage of the term. Fëanor accepted the judgment and withdrew to Formenos, taking his father and the Silmarils with him.
The darkening of Valinor brought him to the centre of events. When Yavanna asked whether the light of the Trees might be rekindled from the Silmarils, and Fëanor answered that to surrender them would be his death and that he would be the first of the Eldar to die in Aman, Mandos remarked only that he would not be the first — a correction whose meaning became plain moments later, when a messenger arrived with the news that Finwë had been slain at Formenos. Afterwards, as the rebel host marched north along the coast of Araman, a dark shape looked down on them from a crag and pronounced the curse and prophecy remembered as the Doom of the Noldor. The accounts do not settle whether this was Mandos in person or a herald speaking with his voice, but the judgment is his in substance and bears his name. Finarfin turned back with a part of his people and received pardon; the rest went on under the sentence.
The Doom set out the terms under which the exiles would live and die: tears beyond counting, treachery of kin against kin, oaths that would drive their swearers to evil, and the fencing of Valinor against their return. It also bound their afterlife, declaring that those slain in Middle-earth would come to the halls of Mandos and there abide long, yearning for their bodies and finding little pity, while those who lingered would grow weary and dwindle. The Wars of Beleriand made the sentence concrete. Fëanor's spirit, when it left him upon the marches of Dor Daedeloth, burned away his body and passed to Mandos, and it was not released again; his house was diminished, and none of the Noldor of that line returned. Not all were held, however: Finrod Felagund, who died in the dungeons of Tol-in-Gaurhoth to keep faith with Beren, was afterwards restored and walked again in Eldamar with his father, which shows the sentence to have been a term of waiting rather than an unalterable end.
The single occasion on which his judgment is said to have been swayed by feeling came with Lúthien. Dying of grief after Beren, she went to the halls and sang there of the sorrows of Elves and Men interwoven, and Mandos was moved to pity as at no other time before or since. He did not act alone: the matter was laid before Manwë, who sought the counsel of Ilúvatar, and the choice returned to Lúthien was to remain in Aman in forgetfulness of grief, or to take up mortal life again with Beren, who had tarried in the halls only briefly, as Men do, awaiting release from the world. She chose the second. Long afterwards, when Eärendil came to Valinor to plead for the peoples of Middle-earth, it was Mandos who stated the law against him, that no mortal might set foot upon the Undying Lands and live; Ulmo answered on the mariner's behalf, and Manwë gave the ruling that spared him. In this, as throughout, Mandos states what stands rather than what he wishes, and the halls named for him continue to gather the Elvish dead after Morgoth's fall.
Role and Powers
The office of Mandos within the government of Arda is judicial rather than territorial. Where Ulmo holds the waters and Yavanna the growing things, he is given no region to rule, and his authority consists in declaration: he sets forth dooms and judgments, and he does so at the bidding of Manwë, who holds the sovereignty of Arda under Ilúvatar. The distinction matters, because it makes his utterances statements of what is appointed rather than decrees of his own devising. He is likewise a keeper as well as a speaker, for the custody both of the Elvish dead and, on occasion, of the Valar's prisoners belongs to his halls. Nothing in the accounts attributes to him feats of arms or the shaping of lands; the might reckoned to him is the might of knowledge and of sentence.
His governance of the dead is bounded by the difference between the Children of Ilúvatar. The spirits of slain Elves are summoned to his halls and gathered there, and they may in time be released and returned to life within Arda, since their fate is bound to the world and endures while it endures. Men are otherwise: they tarry only briefly before departing beyond the circles of the world, and where they go is not known to the Valar, so that over the greater part of their destiny Mandos has no keeping at all. Even for the Eldar his authority is not absolute. Release is granted rather than seized, and the notable reversals recorded of his halls were referred upward, to Manwë and beyond him to Ilúvatar, before they took effect.
The limits set upon his foresight are stated as plainly as its reach. He perceives what is to come by virtue of the Music in which all things were foreshown, but the Music did not contain everything, and what Ilúvatar has kept to himself lies outside that perception. He is further restrained by custom: he withholds what he knows unless Manwë requires it of him, and he does not intervene in counsel of his own motion. When he does speak, the judgment stands as spoken and is not revised, though it may prove, as with the exiled Noldor, to be a term of waiting rather than a final end.
Relationships
The household of Mandos is small and strikingly of a piece with his office. Vairë his spouse is the only Valië whose work is bound to his own: she weaves the story of time as it happens, and her webs are hung within his dwelling, which is said to widen as the ages lengthen and the record grows. Neither of them acts upon events; both preserve them, the one in cloth and the other in sentence. Of his kindred, Irmo his brother holds a domain that is in some sense his opposite, gardens of rest and dream in Valinor rather than a house of waiting, and the two are named together as the masters of spirits. Nienna, reckoned their sister, dwells on the western borders of the world and comes often to the halls, where those who abide there are strengthened by her; what she gives is pity and the turning of grief into wisdom, and it is notable that the accounts assign this to her rather than to him.
Above him stands Manwë, and the relation is one of speech rather than obedience in any servile sense: Mandos declares, but only when the King of Arda has called upon him, and the greatest reversals recorded of his halls were carried upward to Manwë and thence to Ilúvatar. Against this steadiness Ulmo appears twice as the countervailing voice — first in the debate over summoning the Quendi westward, and long after in the plea made for Eärendil — so that the histories set the Lord of Waters, who argues for mercy and for the peoples of Middle-earth, opposite the Doomsman, who states the law as it stands. Neither is described as bearing the other any ill will; the difference is one of function.
He has no personal adversary. Melkor passed three ages under his keeping, yet the custody was Manwë's sentence and the pardon Manwë's ruling, and no exchange between captor and captive is recorded. His dealings with Fëanor and the exiled Noldor are likewise impersonal: he pronounces upon them and afterwards holds them, without recorded anger. The one relation described in terms of feeling is with Lúthien, whose singing moved him to pity as nothing else had; even there, the decision was not his to make.
Drafts and Variants
In the earliest surviving conception, set down in the Lost Tales, the figure is called Vefántur, the Fantur of death, and he is paired with Olofántur, the Fantur of dreams who is Lórien; together they are the Fánturi, an earlier form of the later Fëanturi. His halls bore the name Vê and stood in a region called Mandos, so that the transference of the place-name to its master was present from the beginning, though the geography and the spelling shifted afterwards. The most substantial difference concerns his household: his wife in that version is Fui Nienna, a goddess of death and weeping who herself weighed the fates of Men in her halls, sending some away to the keeping of Melko, while the dusky ship Mornië carried the Elvish dead over the shadowy waters. Nienna's later position as unwedded sister, and Vairë's as spouse, belong to a much later stage; in the Lost Tales the name Vairë is given instead to an Elf-woman of Tol Eressëa. The Quenta texts of the 1930s call him Nurufantur, and the true name Námo entered only with the revisions of the following decades.
Two matters treated at length in the drafts are absent or muted in the published Silmarillion. The Quenta of the 1930s closes with a second prophecy attributed to him, foretelling the last battle, the breaking of the Door of Night, Túrin's part in Morgoth's end and the rekindling of the Two Trees; Christopher Tolkien did not admit it into the published text. Later, in the essays and annals gathered in Morgoth's Ring, his judicial office is developed in far greater detail than the finished narrative preserves, above all in the long debate of the Valar over Finwë and Míriel, where the statute governing death, release and remarriage among the Eldar is framed and pronounced by him, and where Míriel is at last permitted to return and to weave in the service of Vairë. The same body of writing records Tolkien's growing dissatisfaction with the doctrine that released spirits were reborn as children, which he moved to replace with the rebuilding of the body by the Valar.
