In 55 BC, the Roman poet Catullus began writing personal lyric poetry, a genre characterized by intimate and passionate expressions of emotion. His verses, particularly those addressed to his lover Lesbia, broke from traditional epic poetry, focusing instead on personal experiences and feelings. Catullus's work significantly influenced later poets and is considered a precursor to modern lyric poetry, highlighting the importance of individual voice in literature.

Catullus's personal lyric poetry, written around 55 BC, pioneered a new subjective style that emphasized emotional depth and personal voice. His intimate verses laid the groundwork for later European poets, influencing the development of confessional poetry and the exploration of personal relationships.
