Historical source

In their old ballads (which amongst them are the only sort of registers and history) they celebrate Tuisto, a God sprung from the earth, and Mannus his son, as the fathers and founders of the nation. To Mannus they assign three sons, after whose names so many people are called; the Ingaevones, dwelling next the ocean; the Herminones, in the middle country; and all the rest, Instaevones.
(Tacito, Germania)

They have a tradition that Hercules also had been in their country, and him above all other heroes they extol in their songs when they advance to battle.
(Tacito, Germania)

Of all the Gods, Mercury is he whom they worship most. To him on certain stated days it is lawful to offer even human victims. Hercules and Mars they appease with beasts usually allowed for sacrifice. Some of the Suevians make likewise immolations to Isis. Concerning the cause and original of this foreign sacrifice I have found small light; unless the figure of her image formed like a galley, show that such devotion arrived from abroad. For the rest, from the grandeur and majesty of beings celestial, they judge it altogether unsuitable to hold the Gods enclosed within walls, or to represent them under any human likeness. They consecrate whole woods and groves, and by the names of the Gods they call these recesses; divinities these, which only in contemplation and mental reverence they behold.
(Tacito, Germania)

To the use of lots and auguries, they are addicted beyond all other nations. Their method of divining by lots is exceeding simple. From a tree which bears fruit they cut a twig, and divide it into two small pieces. These they distinguish by so many several marks, and throw them at random and without order upon a white garment. Then the Priest of the community, if for the public the lots are consulted, or the father of a family if about a private concern, after he has solemnly invoked the Gods, with eyes lifted up to heaven, takes up every piece thrice, and having done thus forms a judgment according to the marks before made. If the chances have proved forbidding, they are no more consulted upon the same affair during the same day; even when they are inviting, yet, for confirmation, the faith of auguries too is tried. Yea, here also is the known practice of divining events from the voices and flight of birds. But to this nation it is peculiar, to learn presages and admonitions divine from horses also. These are nourished by the State in the same sacred woods and grooves, all milk-white and employed in no earthly labour. These yoked in the holy chariot, are accompanied by the Priest and the King, or the Chief of the community, who both carefully observed his actions and neighing.
(Tacito, Germania)

Their wives, who would accompany them on their expeditions, were attended by priestesses who were seers; these were grey-haired, clad in white, with flaxen cloaks fastened on with clasps, girt with girdles of bronze, and bare-footed; now sword in hand these priestesses would meet with the prisoners of war throughout the camp, and having first crowned them with wreaths would lead them to a brazen vessel of about twenty amphorae; and they had a raised platform which the priestess would mount, and then, bending over the kettle, would cut the throat of each prisoner after he had been lifted up; and from the blood that poured forth into the vessel some of the priestesses would draw a prophecy, while still others would split open the body and from an inspection of the entrails would utter a prophecy of victory for their own people; and during the battles they would beat on the hides that were stretched over the wicker-bodies of the wagons and in this way produce an unearthly noise.
(Strabone, Liber VII)

WAR

Amongst them too are found that kind of verses by the recital of which (by them called Barding) they inspire bravery; nay, by such chanting itself they divine the success of the approaching fight. For, according to the different din of the battle they urge furiously, or shrink timorously. Nor does what they utter, so much seem to be singing as the voice and exertion of valour. They chiefly study a tone fierce and harsh, with a broken and unequal murmur, and therefore apply their shields to their mouths, whence the voice may by rebounding swell with greater fullness and force.
(Tacito, Germania)

Neither in truth do they abound in iron, as from the fashion of their weapons may be gathered. Swords they rarely use, or the larger spear. They carry javelins or, in their own language, frameas, pointed with a piece of iron short and narrow, but so sharp and manageable, that with the same weapon they can fight at a distance or hand to hand, just as need requires. Nay, the horsemen also are content with a shield and a javelin. The foot throw likewise weapons missive, each particular is armed with many, and hurls them a mighty space, all naked or only wearing a light cassock. In their equipment they show no ostentation; only that their shields are diversified and adorned with curious colours. With coats of mail very few are furnished, and hardly upon any is seen a headpiece or helmet. Their horses are nowise signal either in fashion or in fleetness; nor taught to wheel and bound, according to the practice of the Romans: they only move them forward in a line, or turn them right about, with such compactness and equality that no one is ever behind the rest. To one who considers the whole it is manifest, that in their foot their principal strength lies, and therefore they fight intermixed with the motions and engagements of the cavalry. So that the infantry are elected from amongst the most robust of their youth, and placed in front of the army. The number to be sent is also ascertained, out of every village an hundred, and by this very name they continue to be called at home, those of the hundred band: thus what was at first no more than a number, becomes thenceforth a title and distinction of honour. In arraying their army, they divide the whole into distinct battalions formed sharp in front. To recoil in battle, provided you return again to the attack, passes with them rather for policy than fear. Even when the combat is no more than doubtful, they bear away the bodies of their slain. The most glaring disgrace that can befall them, is to have quitted their shield; nor to one branded with such ignominy is it lawful to join in their sacrifices, or to enter into their assemblies; and many who had escaped in the day of battle, have hanged themselves to put an end to this their infamy.
(Tacito, Germania)

In history we find, that some armies already yielding and ready to fly, have been by women restored, through their inflexible importunity and entreaties, presenting their breasts, and showing their impending captivity; an evil to the Germans then by far most dreadful when it befalls their women. So that the spirit of such cities as amongst their hostages are enjoined to send their damsels of quality, is always engaged more effectually than that of others. They even believe them endowed with something celestial and the spirit of prophecy. Neither do they disdain to consult them, nor neglect the responses which they return.
(Tacito, Germania)

In the choice of kings they are determined by the splendour of their race, in that of generals by their bravery. Neither is the power of their kings unbounded or arbitrary: and their generals procure obedience not so much by the force of their authority as by that of their example, when they appear enterprising and brave, when they signalise themselves by courage and prowess; and if they surpass all in admiration and pre-eminence, if they surpass all at the head of an army. But to none else but the Priests is it allowed to exercise correction, or to inflict bonds or stripes. Nor when the Priests do this, is the same considered as a punishment, or arising from the orders of the general, but from the immediate command of the Deity, Him whom they believe to accompany them in war. They therefore carry with them when going to fight, certain images and figures taken out of their holy groves. What proves the principal incentive to their valour is, that it is not at random nor by the fortuitous conflux of men that their troops and pointed battalions are formed, but by the conjunction of whole families, and tribes of relations. Moreover, close to the field of battle are lodged all the nearest and most interesting pledges of nature. Hence they hear the doleful howlings of their wives, hence the cries of their tender infants. These are to each particular the witnesses whom he most reverences and dreads; these yield him the praise which affect him most. Their wounds and maims they carry to their mothers, or to their wives, neither are their mothers or wives shocked in telling, or in sucking their bleeding sores. Nay, to their husbands and sons whilst engaged in battle, they administer meat and encouragement.
(Tacito, Germania)

From the nation with whom they are at war they contrive, it avails not how, to gain a captive: him they engage in combat with one selected from amongst themselves, each armed after the manner of his country, and according as the victory falls to this or to the other, gather a presage of the whole.
(Tacito, Germania)

In the day of battle, it is scandalous to the Prince to be surpassed in feats of bravery, scandalous to his followers to fail in matching the bravery of the Prince. But it is infamy during life, and indelible reproach, to return alive from a battle where their Prince was slain. To preserve their Prince, to defend him, and to ascribe to his glory all their own valorous deeds, is the sum and most sacred part of their oath. The Princes fight for victory; for the Prince his followers fight.
(Tacito, Germania)

That Caesar might enter the lists when he chose; he would feel what the invincible Germans, well-trained [as they were] beyond all others to arms, who for fourteen years had not been beneath a roof, could achieve by their valour.
(Cesare, De Bello Gallico)

For five successive days from that day, Caesar drew out his forces before the camp, and put them in battle order, that, if Ariovistus should be willing to engage in battle, an opportunity might not be wanting to him. Ariovistus all this time kept his army in camp: but engaged daily in cavalry skirmishes. The method of battle in which the Germans had practiced themselves was this. There were 6,000 horse, and as many very active and courageous foot, one of whom each of the horse selected out of the whole army for his own protection. By these [foot] they were constantly accompanied in their engagements; to these the horse retired; these on any emergency rushed forward; if any one, upon receiving a very severe wound, had fallen from his horse, they stood around him: if it was necessary to advance further than usual, or to retreat more rapidly, so great, from practice, was their swiftness, that, supported by the manes of the horses, they could keep pace with their speed.
(Cesare, De Bello Gallico)

When Caesar inquired of his prisoners, wherefore Ariovistus did not come to an engagement, he discovered this to be the reason-that among the Germans it was the custom for their matrons to pronounce from lots and divination, whether it were expedient that the battle should be engaged in or not; that they had said, “that it was not the will of heaven that the Germans should conquer, if they engaged in battle before the new moon.
(Cesare, De Bello Gallico)

Then at last of necessity the Germans drew their forces out of camp, and disposed them canton by canton, at equal distances, the Harudes, Marcomanni, Tribocci, Vangiones, Nemetes, Sedusii, Suevi; and surrounded their whole army with their chariots and wagons, that no hope might be left in flight. On these they placed their women, who, with dishevelled hair and in tears, entreated the soldiers, as they went forward to battle, not to deliver them into slavery to the Romans.
(Cesare, De Bello Gallico)

But the Germans, according to their custom, rapidly forming a phalanx, sustained the attack of our swords.
(Cesare, De Bello Gallico)

according to their practice, is anything regarded as more unseemly, or more unmanly, than to use housings. Accordingly, they have the courage, though they be themselves but few, to advance against any number whatever of horse mounted with housings
(Cesare, De Bello Gallico)

“That the Germans neither make war upon the Roman people first, nor do they decline, if they are provoked, to engage with them in arms; for that this was the custom of the Germans handed down to them from their forefathers, to resist whatsoever people make war upon them and not to avert it by entreaty.
(Cesare, De Bello Gallico)

But the enemy, as soon as they saw our horse, the number of which was 5000, whereas they themselves had not more than 800 horse, because those which had gone over the Meuse for the purpose of foraging had not returned, while our men had no apprehensions, because their ambassadors had gone away from Caesar a little before, and that day had been requested by them as a period of truce, made an onset on our men, and soon threw them into disorder. When our men, in their turn, made a stand, they, according to their practice, leaped from their horses to their feet, and stabbing our horses in the belly and overthrowing a great many of our men, put the rest to flight, and drove them forward so much alarmed that they did not desist from their retreat till they had come in sight of our army.
(Cesare, De Bello Gallico)

PHYSICAL ASPECT

Hence amongst such a mighty multitude of men, the same make and form is found in all, eyes stern and blue, yellow hair, huge bodies, but vigorous only in the first onset. Of pains and labour they are not equally patient, nor can they at all endure thrift and heat. To bear hunger and cold they are hardened by their climate and soil.
(Tacito, Germania)

For their covering a mantle is what they all wear, fastened with a clasp or, for want of it, with a thorn. As far as this reaches not they are naked, and lie whole days before the fire. The most wealthy are distinguished with a vest, not one large and flowing like those of Sarmatians and Parthians, but girt close about them and expressing the proportion of every limb. They likewise wear the skins of savage beasts, a dress which those bordering upon the Rhine use without any fondness or delicacy, but about which such who live further in the country are more curious, as void of all apparel introduced by commerce. They choose certain wild beasts, and, having flayed them, diversify their hides with many spots, as also with the skins of monsters from the deep, such as are engendered in the distant ocean and in seas unknown. Neither does the dress of the women differ from that of the men, save that the women are orderly attired in linen embroidered with purple, and use no sleeves, so that all their arms are bare. The upper part of their breast is withal exposed.
(Tacito, Germania)

Whilst he is tarrying a few days at Vesontio, on account of corn and provisions; from the inquiries of our men and the reports of the Gauls and traders, who asserted that the Germans were men of huge stature, of incredible valour and practice in arms, that often they, on encountering them, could not bear even their countenance, and the fierceness of their eyes)—so great a panic on a sudden seized the whole army, as to discompose the minds and spirits of all in no slight degree.
(Cesare, De Bello Gallico)

Now the parts beyond the Rhenus, immediately after the country of the Celts, slope towards the east and are occupied by the Germans, who, though they vary slightly from the Celtic stock in that they are wilder, taller, and have yellower hair, are in all other respects similar, for in build, habits, and modes of life they are such as I have said the Celts are.
(Strabone, Libro VII)

FOOD AND DRINK

For their drink, they draw a liquor from barley or other grain; and ferment the same so as to make it resemble wine. Nay, they who dwell upon the bank of the Rhine deal in wine. Their food is very simple; wild fruit, fresh venison, or coagulated milk. They banish hunger without formality, without curious dressing and curious fare. In extinguishing thirst, they use not equal temperance. If you will but humour their excess in drinking, and supply them with as much as they covet, it will be no less easy to vanquish them by vices than by arms.
(Tacito, Germania)

They on no account permit wine to be imported to them, because they consider that men degenerate in their powers of enduring fatigue, and are rendered effeminate by that commodity.
(Cesare, De Bello Gallico)

EVERYDAY LIFE

They sit down as they list, promiscuously, like a crowd, and all armed. It is by the Priests that silence is enjoined, and with the power of correction the Priests are then invested. Then the King or Chief is heard, as are others, each according to his precedence in age, or in nobility, or in warlike renown, or in eloquence; and the influence of every speaker proceeds rather from his ability to persuade than from any authority to command. If the proposition displease, they reject it by an inarticulate murmur: if it be pleasing, they brandish their javelins. The most honourable manner of signifying their assent, is to express their applause by the sound of their arms.
(Tacito, Germania)

Without being armed they transact nothing, whether of public or private concernment. But it is repugnant to their custom for any man to use arms, before the community has attested his capacity to wield them. Upon such testimonial, either one of the rulers, or his father, or some kinsman dignify the young man in the midst of the assembly, with a shield and javelin. This amongst them is the manly robe, this first degree of honour conferred upon their youth. Before this they seem no more than part of a private family, but thenceforward part of the Commonweal. The princely dignity they confer even upon striplings, whose race is eminently noble, or whose fathers have done great and signal services to the State. For about the rest, who are more vigorous and long since tried, they crowd to attend; nor is it any shame to be seen amongst the followers of these. Nay, there are likewise degrees of followers, higher or lower, just as he whom they follow judges fit. Mighty too is the emulation amongst these followers, of each to be first in favour with his Prince; mighty also the emulation of the Princes, to excel in the number and valour of followers. This is their principal state, this their chief force, to be at all times surrounded with a huge band of chosen young men, for ornament and glory in peace, for security and defence in war. Nor is it amongst his own people only, but even from the neighbouring communities, that any of their Princes reaps so much renown and a name so great, when he surpasses in the number and magnanimity of his followers. For such are courted by Embassies, and distinguished with presents, and by the terror of their fame alone often dissipate wars.
