caption_attribution_description: English: One of the painters commissioned to make a ‘Batavian’ painting for the new Amsterdam town hall was Rembrandt van Rijn (1606-69). Rembrandt chose the moment of the oath of the Batavians in the sacred grove, as described by Tacitus, Histories IV, 14. Civilis, with crown and sword, is the main protagonist of the composition. Unlike his fellow painters, Rembrandt decided to depict Civilis with one blind eye, as some of the sources had described his appearance. In 1662 it was reportedly on display at the town hall, but shortly afterwards, it was removed from the building. The painting, originally measuring more than 5 by 5 metres, was reduced to about 2 by 3 metres, which incidentally makes Civilis`s blind eye more clearly visible.
context_page_description: The Batavi were an ancient Germanic tribe that lived around the modern Dutch Rhine delta in the area that the Romans called Batavia, from the second half of the first century BC to the third century AD. The name is also applied to several military units employed by the Romans that were originally raised among the Batavi. The tribal name, probably a derivation from batawjō, refers to the region's fertility, today known as the fruitbasket of the Netherlands.
  Finds of wooden tablets show that at least some were literate.
context_section_description: The first Batavi commander we know of is named Chariovalda, who led a charge across the Vīsurgis (Weser) river against the Cherusci led by Arminius during the campaigns of Germanicus in Germania Transrhenana.
  Tacitus (De origine et situ Germanorum XXIX) described the Batavi as the bravest of the tribes of the area, hardened in the Germanic wars, with cohorts under their own commanders transferred to Britannia. They retained the honour of the ancient association with the Romans, not required to pay tribute or taxes and used by the Romans only for war: "They furnished to the Empire nothing but men and arms", Tacitus remarked. Well regarded for their skills in horsemanship and swimming—for men and horses could cross the Rhine without losing formation, according to Tacitus. Dio Cassius describes this surprise tactic employed by Aulus Plautius against the "barbarians"—the British Celts— at the battle of the River Medway, 43:
  The barbarians thought that Romans would not be able to cross it without a bridge, and consequently bivouacked in rather careless fashion on the opposite bank; but he sent across a detachment of Germanic tribesmen, who were accustomed to swim easily in full armour across the most turbulent streams. [...] Thence the Britons retired to the river Thames at a point near where it empties into the ocean and at flood-tide forms a lake. This they easily crossed because they knew where the firm ground and the easy passages in this region were to be found; but the Romans in attempting to follow them were not so successful. However, the Germans swam across again and some others got over by a bridge a little way up-stream, after which they assailed the barbarians from several sides at once and cut down many of them. (Cassius Dio, Roman History, Book 60:20)
  It is uncertain how they were able to accomplish this feat. The late 4th century writer on Roman military affairs Vegetius mentions soldiers using reed rafts, drawn by leather leads, to transport equipment across rivers. But the sources suggest the Batavi were able to swim across rivers actually wearing full armour and weapons. This would only have been possible by the use of some kind of buoyancy device: Ammianus Marcellinus mentions that the Cornuti regiment swam across a river floating on their shields "as on a canoe" (357). Since the shields were wooden, they may have provided sufficient buoyancy
  The Batavi were used to form the bulk of the Emperor's personal Germanic bodyguard from Augustus to Galba. They also provided a contingent for their indirect successors, the Emperor's horse guards, the Equites singulares Augusti.
  A Batavian contingent was used in an amphibious assault on Ynys Mon (Anglesey), taking the assembled Druids by surprise, as they were only expecting Roman ships.
  Numerous altars and tombstones of the cohorts of Batavi, dating to the 2nd century and 3rd century, have been found along Hadrian's Wall, notably at Castlecary and Carrawburgh. As well as in Germany, Yugoslavia, Hungary, Romania and Austria.
