Part 1

Germanicus is not a name that many people are familiar with today, but the man and his family are central figures in the story of one of the most colourful imperial dynasties the world has ever known – the Julio-Claudians.

The Julio-Claudians get their name from two families of the old Roman republic. Both families were old. The Julians had an impeccable aristocratic pedigree, while the Claudians were one of the most politically powerful families in the state. The two were thrown together into an alliance during the troubles which gripped Rome during the fall of the Republic.

The Family of Germanicus

Germanicus is not a name that many people are familiar with today, but the man and his family are central figures in the story of one of the most colourful imperial dynasties the world has ever known – the Julio-Claudians.

The Julio-Claudians get their name from two families of the old Roman republic. Both families were old. The Julians had an impeccable aristocratic pedigree, while the Claudians were one of the most politically powerful families in the state. The two were thrown together into an alliance during the troubles which gripped Rome during the fall of the Republic.

Julius Caesar, the most famous member of the Julian family, led his legions in the conquest of Rome. Though Caesar was a great general, he lacked the political skills to control the Roman senate and Caesar was killed by the senators during one of their meetings. Another round of civil wars followed, and Caesar's great-nephew, Augustus, became the ruler of Rome.

In contrast to Caesar, Augustus was a superb, uncompromising and ruthless politician. Early in his career he realized that his family could not rule alone, and he allied himself with the Claudians by marrying a woman called Livia Drusilla. Livia was not only a Claudian herself, but the former wife of another Claudian. She had two children by her first marriage, Tiberius and Drusus.

When he grew up, Drusus married Antonia, the daughter of Mark Antony. They had two children, one called Claudius and the other named Tiberius after his uncle and grandfather (Tiberius was a common Roman name, and often used for members of the Claudian family.)

Tiberius joined the army while he was still a young man, and turned out to be an excellent soldier. At the time, the Romans were busy with a major war in Germany. This war had not been going well, and the Romans lost a number of legions during a major battle in the Teutonwald forest. Tiberius was one of the commanders who helped to restore the power of Rome, and to celebrate his victories, and to distinguish him from his uncle, the soldiers started calling him Germanicus.

Germanicus, or Nero Claudius Drusus Germanicus to give him his proper name, was not only an excellent commander, but one who took great care that his soldiers were well supplied and looked after. He was loved by the troops he commanded and this love helped him to bring the legions back under control when they mutinied on hearing of the death of Augustus.

Since Augustus had no sons he had adopted Tiberius, the uncle of Germanicus. As the son of Augustus, Tiberius became emperor after him. Augustus had known how popular Germanicus was, and considered adopting him instead of Tiberius, but instead adopted Tiberius and made Tiberius adopt Germanicus. His plan was that power should go from himself, to Tiberius and then to Germanicus and his sons. Germanicus had already become closer to the Julian family by his marriage to Agrippina, the grand-daughter of Augustus.

Sadly, the glittering career of Germanicus did not happen. From Germany he want to Asia Minor where he again won victories for Rome, but on his return from a trip to Egypt he became ill and died. Some modern historians believe that Germanicus died of malaria, but Germanicus and his wife were both convinced that he had been poisoned by his enemies. Among those they suspected was Tiberius, the emperor, since it was felt he wanted power to pass to his own son rather than to Germanicus.

With the clear line of succession destroyed, members of the imperial court started to plot and scheme to see who would be emperor after Tiberius, who was already an old man. The conspiracies drew in the surviving members of the family of Germanicus, and the two eldest boys were accused of treason and killed. One daughter, Julia Livilla, was married to the son of Tiberius and is believed to have poisoned him – partly to help the plots of her lover and partly to avenge the 'poisoning' of her father. Agrippina, the wife of Germanicus was exiled and starved herself to death.

One boy survived, a young man called Gaius. Tiberius made him live in his house where he could watch him carefully, but also because Tiberius was true to his promise that when he died the children of Germanicus would come to power. Gaius did indeed become emperor, but the mental stress of the earlier years could not be undone, and he is known today as the mad emperor Caligula.

Gaius Caligula was assassinated, but history had not done with the children of Germanicus. The next emperor was Claudius, the brother of Germanicus. He married, another daughter of Germanicus called Agrippina after her mother. Agrippina, a direct descendant of Augustus, was thus the wife and niece of Claudius, the sister of Caligula, and eventually, the mother of another emperor. This was Nero, the tyrant emperor whose death marked the end of the descendants of Germanicus and the Julio-Claudian dynasty of emperors.

Gondwanaland

Meet Mesosaurus, a small reptile which lived in fresh-water lakes and streams millions of years ago during the lower Permain age. Mesosaurus has had a big impact on how we view our planet, because he helped to prove the existence of the super-continent called Gondwanaland.

Every schoolchild has probably looked at a map of the earth and noticed how Africa and South America fit together like pieces of a giant jigsaw, yet until just over a hundred and fifty years ago, no-one believed that this was more than an odd coincidence. It seemed impossible that the massive continents of the earth could ever be moved, let alone so far apart that they ended up half a planet from each other.

Nevertheless, in 1912 Alfred Wegener, a German meteorologist came up with the theory that the continents of the earth had all existed in a single mass, which he called Pangaea (which is Greek for 'all the world'') Later researchers decided that Pangaea had been two continents, one to the north of the other, which had existed about 250 million years ago. From the geological evidence found in the Gondwana area of India, an Austrian geologist, Eduard Suess coined the name 'Gondwanaland' for the southern supercontinent, of which India was once a part. (The northern continent was called Lurasia.)

For many years super-continents were regarded as an interesting theory, but no-one knew how it might work in reality. Then the discovery of the mechanisms of plate tectonics showed how continents might drift across the face of the globe. Once it was accepted that the continents were floating on currents of lava, more evidence became apparent. A particular type of an early plant, the seed fern, was found on continents now scattered about the southern hemisphere of the world, as were tillates, a deposit left by glaciers in the Permo-Carboniferous era of 520 million years ago. And Mesosaurus, the little fresh-water reptile, left his remains in West Africa and Brazil. Since Mesosaurus had no way of crossing the Atlantic, researchers realized that it could not be coincidence that this reptile had left remains in exactly the place where Africa and South America fit together so neatly.

By investigating similarities in animal fossils, different types of plants found in the southern hemisphere but not in the northern hemisphere, and patterns of rock formations, researchers have managed to put the continents of modern-day earth together like a huge jigsaw to make up the vanished super-continent. Sometimes rock formations can be seen to break off at the ocean's edge, to carry on once more thousands of miles away on another continent. The evidence shows that not only were Africa and South America once joined to Antartica, but so were India and Australia, parts of south Western Europe, and Florida.

Although Gondwanaland was located in the far southern hemisphere of the planet, where Antarctica remains today, the climate was much warmer, and we know that huge forests grew there. These forests, fossilized into coal, supply many Indians with energy today. The land animals were adapted to life on their cool continent, with its long dark winter days. Some of the best known dinosaurs, such as Stegosaurus, Triceratops, and Tyrannosaurus lived on the northern continents, but Gondwanaland also had some fearsome predators such as Abelisaurus, a large meat-eater that lived during the cretaceous period. The seas were populated with fish called placoderms, a name which they get from their skin, which was so thick that they were practically armoured.

The break-up of Gondwanaland had huge consequences for planet earth as we know it now. In geological terms, India has been a sprinter. Breaking from Gondwanaland the sub-continent drifted rapidly northward from the south pole, finally smashing into Asia about 45 million years ago in a collision that raised the Himalayas.

When South America split off about 30 million years ago the effect was even more dramatic. Cold Antarctic water no longer mixed with warmer seas when pushed northward by the south American landmass. Instead it circled the pole getting colder and colder, until Antartica lost its vegetation and animal life, and became the barren icy wilderness it is today.
