Of Catullus' life little is known for sure. He was born on the Palatine hill of Rome. He was an offspring of a leading family from Verona, but lived in Rome most of his life. In 57 B.C., he accompanied his friend Memmius to Bithynia, where Memmius had received a propraetor's post. Catullus himself, however, never held a political office.
His poetry was greatly influenced by the Greek neoteroi, especially by Callimachus, who propagated a new style of poetry, deliberately turning away from the classical epic poetry in the tradition of Homer. Their poems no longer described the feats of ancient heroes and gods but concentrated on small-scale personal themes. Although these poems sometimes seem quite superficial and their subject often are mere everyday concerns, they nevertheless are accomplished works of art.
The work of Catullus was handed down as an anthology of 116 carmina (presumably not arranged by the author), which can be divided into three formal parts: 60 short poems in varying metres, called polymetra, 8 longer poems and 48 epigrams.
The longer poems differ from the polymetra and the epigrams not only in length but also in their subjects: They are hymns and one mini-epic.
The polymetra and the epigrams can be divided into three major thematical groups (ignoring a rather large number of poems eluding such categorization):
All these poems describe the rather Epicurean lifestyle of Catullus and his friends, who lived withdrawn from (though not oblivious to) politics. They were mainly interested in poetry and love, and the ancient Roman concept of virtus (i.e. of virtue that had to be proved either by a political career or by military valor), which Cicero propagated as the solution to the societal problems of the late Republic, meant nothing to them.
But it is not actually the traditional notions Catullus rejects, but merely their monopolized application to the vita activa of politics and war. Indeed, he tries to reinvent these notions from a personal point of view and to introduce them into human relationship. For example, he applies the word fides, which traditionally meant faithfulness towards one's political allies, to his relationship to Lesbia and reinterprets it as unconditional faithfulness in love. So, despite his seemingly frivolous lifestyle Catullus measured himself and his friends by quite ambitious standards.
It isn't known for sure when Catullus died, some antique sources tell he died from exhaustion at the age of 30. Subsequently, his poems were appreciated by other poets and intellectuals, but politicians like Cicero despised them because of their amorality, and Catullus was not considered one of the canonical school authors. Nevertheless, he greatly influenced later poets like Ovid, Horace and even Virgil and after his rediscovery in the Middle Ages, he again found admirers. Still his sometimes quite explicit writing style was shocking to many readers, antique and modern ones, and even today it is not easy to find an equally explicit translation of some of his poems.

Could somebody please check the poetological and philosophical terms? I only know their German forms and I had to guess on the English translations...
