Sources and organization

• poems to and about his friends (e.g., an invitation like poem 13).
• erotic poems: some of them indicate homosexual penchants (50 and 99), but most are about women, especially about one he calls "Lesbia" (in honour of the poetess Sappho of Lesbos, source and inspiration of many of his poems).
• invectives: often rude and sometimes downright obscene poems targeted at friends-turned-traitors (e.g., poem 30), other lovers of Lesbia, well known poets, politicians (e.g., Julius Caesar) and rhetors, including Cicero.
• condolences: some poems of Catullus are solemn in nature. 96 comforts a friend in the death of a loved one; several others, most famously 101, lament the death of his brother.

Intellectual influences

Style

• The epistolary novel Ides of March by Thornton Wilder centers on Julius Caesar, but prominently features Catullus, his poetry, his relationship (and correspondence) with Clodia, correspondence from his family and a description of his death. Catullus's poems and the closing section by Suetonius are the only documents in the novel which are not imagined.
• Catulli Carmina is a cantata by Carl Orff to the texts of Catullus.
• The new musical TULLY (In No Particular Order), which appeared in the 2007 New York Musical Theatre Festival, loosely adapts the poems of Catullus while retaining the non-linear structure of the published edition, exploring his relationships with both Clodia and Juventius, renamed Julie, and the timeless nature of memory and love.
• The 20th-century Irish poet Louis MacNeice references Catullus in his poem "Epitaph for Liberal Poets," where he mentions Catullus as amongst the first liberal poets - "Catullus/ went down young," mentioning him in the context of the death of the individual and recognising his and the universal plight.
• Archibald MacLeish wrote a poem entitled "You Also, Gaius Valerius Catullus," where he addresses the poet.
• Catullus is discussed in John Fowles's novel The French Lieutenant's Woman (1969) as being one of the foremost poets of love, sexuality and desire.
• The 16th-century Spanish poet Cristóbal de Castillejo plagiarized Catullus in his well-known work "Dame amor, besos sin cuento".
• Yeats references Catullus in his poem The Scholars.
• Ned Rorem has a song entitled, "Catullus: On the burial of his brother."
