What is "tibullus"

Albius Tibullus (; c. 55 BC – 19 BC) was a Latin poet and writer of elegies. Little is known about his life. His first and second books of poetry are extant; many other texts attributed to Tibullus are of questionable origins. There are only a few references to him in later writers and a short Life of doubtful authority. His praenomen is not known, nor is his birthplace and his gentile name has been questioned. His status was probably that of a Roman knight (so the Life affirms); and he had inherited a considerable estate. But, like Virgil, Horace and Propertius, he seems to have lost most of it in 41 BC amongst the confiscations of Mark Antony and Octavian.
