Catullus 5 turns a private appeal to Lesbia into an argument: public criticism is worthless, human life does not return as the sun does, and therefore love must be lived now. The grammar carries that movement. Shared hortatory subjunctives become an urgent imperative, a gerundive makes death inescapable, and a cascade of numerals dissolves into deliberate uncountability.
“Lesbia” is a literary pseudonym. She is often identified with Clodia, but the poem itself does not name Clodia, so that identification should not be treated as grammar or as certainty. The poem is (literary) and playful; forms such as mī for mihi and its tightly patterned word order should be recognized in verse rather than copied indiscriminately into ordinary prose.
The complete poem
The quotation is Catullus, Carmina 5.1–13. It is printed without added macrons so that the ancient text is not silently turned into a teaching edition.
Vivamus, mea Lesbia, atque amemus,
rumoresque senum severiorum
omnes unius aestimemus assis.
Soles occidere et redire possunt:
nobis, cum semel occidit brevis lux,
nox est perpetua una dormienda.
Da mi basia mille, deinde centum,
dein mille altera, dein secunda centum,
deinde usque altera mille, deinde centum.
Dein, cum milia multa fecerimus,
conturbabimus illa, ne sciamus,
aut ne quis malus invidere possit,
cum tantum sciat esse basiorum.
The poem uses Phalaecian hendecasyllables, treated in detail on Hendecasyllabic Meter. Its normal eleven-position shape is x x | – ⏑ ⏑ | – ⏑ | – ⏑ | – x; Catullus normally fills the opening here heavily. Do not confuse eleven metrical positions with eleven written vowels: elision, as in Lesbi(a) atque, keeps the line within its pattern. Rhythm gives the argument a quick, speech-like drive, but this is quantitative meter—vowel length and syllable weight—not English stress verse.
‘Let us live and love’: the shared decision
Vivamus, mea Lesbia, atque amemus, rumoresque senum severiorum omnes unius aestimemus assis.
Let us live, my Lesbia, and let us love, and let us value all the gossip of rather stern old men at a single as. (Catullus 5.1–3)
vīvāmus and amēmus are first-person plural present subjunctives used hortatorily: “let us …” Catullus includes both speaker and addressee in one proposal. English adds “let”; Latin expresses the invitation in the verb endings themselves. The vocative phrase mea Lesbia interrupts the first clause. Feminine mea agrees with Lesbia, and its placement makes intimacy the bridge between living and loving.
The two verbs are not loose synonyms. vīvere frames a whole way of life; amāre gives that life its chosen action. The balanced endings make the ethical claim sound mutual rather than like an order imposed on Lesbia.
Public talk priced at one coin
Rumoresque senum severiorum omnes unius aestimemus assis.
And let us value all the gossip of rather stern old men at a single as. (Catullus 5.2–3)
The third hortatory subjunctive, aestimēmus, continues the lovers' shared policy. Its direct object is discontinuous: rūmōrēs … omnēs, “all the rumors.” Between noun and adjective stands genitive senum sevēriōrum, “of rather stern old men.” Comparative sevēriōrum can carry the softened or slightly ironic force “rather too stern.”
ūnīus assis is a genitive of value. An as was a low-value bronze monetary unit, so the phrase means “value at one penny”—in idiomatic English, “not give a penny for.” Word order makes the audience wait until the end for the contemptuous price. The elders' supposedly weighty judgment is grammatically reduced to one cheap coin.
Renewable suns, one human light
Soles occidere et redire possunt; nobis cum semel occidit brevis lux …
Suns can set and return; for us, once our brief light has set … (Catullus 5.4–5)
Plural sōlēs means recurring days or sunsets, not multiple astronomical suns. possunt governs two present infinitives, occidere and redīre, whose opposition enacts the cycle. The statement is general: nature can repeat what humans cannot.
Nobis, cum semel occidit brevis lux, nox est perpetua una dormienda.
For us, once our brief light has set, one everlasting night must be slept. (Catullus 5.5–6)
This is the poem's grammatical center. nōbīs is dative of agent with the gerundive construction nox … dormienda [est]: the night must be slept “by us.” It can also be felt as a dative of reference at the beginning of the contrast, “as for us.” nox is feminine nominative, so dormienda agrees with it; it is not an accusative object.
In cum semel occidit brevis lux, brevis lux is the subject. The unmacronized written form occidit could visually represent present occidit or perfect occīdit, but the hendecasyllabic meter requires the short penultimate vowel here: Catullus has the present. English can still render the future-relative event as “once our brief light has set”; the Latin pictures the light's setting as the trigger for what follows. Adjectives brevis and perpetua frame the line boundary: brief light gives way to perpetual night, while semel is answered by ūna, one and only.
The arithmetic of kisses
Da mi basia mille, deinde centum.
Give me a thousand kisses, then a hundred. (Catullus 5.7)
After collective “let us,” Catullus switches to singular imperative dā. mī is a shorter (poetic/archaic) dative form beside mihi. Neuter plural bāsia is the direct object. mīlle is indeclinable in the singular-number use “a thousand”; centum is also indeclinable. The colloquial-sounding bāsium, rather than a ceremonious word for a kiss, helps the voice feel intimate.
Dein mille altera, dein secunda centum, deinde usque altera mille, deinde centum.
Then another thousand, then a second hundred, then continuously another thousand, then a hundred. (Catullus 5.8–9)
Neuter plural altera modifies understood bāsia: “another [set of] a thousand kisses.” Likewise secunda centum means “a second hundred.” The alternation of dein/deinde, mīlle/centum, and altera/secunda imitates excited counting. The grammar is comprehensible, but the sequence is designed to outrun orderly bookkeeping.
Poetic placement separates adjectives from what English expects them to modify. Do not force altera to agree with singular mīlle; it is neuter plural because the understood counted noun bāsia is neuter plural.
Counting so that no one can count
Dein, cum milia multa fecerimus, conturbabimus illa, ne sciamus.
Then, when we have made many thousands, we shall muddle them up so that we do not know. (Catullus 5.10–11)
Plural noun mīlia takes genitive when its counted item is expressed—mīlia bāsiōrum, “thousands of kisses”—though here the kisses are understood. fēcerīmus is formally ambiguous between future perfect indicative and perfect subjunctive: by Catullus's period, long and short i could occur in these overlapping forms. With future conturbābimus and purely temporal cum, it functions as future perfect and locates a completed future action: “when we have made.” Context, not a classroom quantity contrast by itself, resolves the morphology.
Negative purpose clause nē sciāmus explains why they will scramble the totals. The paradox is deliberate: the poem has counted obsessively in order to reach a number it can erase.
Aut ne quis malus invidere possit, cum tantum sciat esse basiorum.
Or so that no malicious person can cast an envious eye, when he knows that there are so many kisses. (Catullus 5.12–13)
aut nē coordinates a second negative purpose clause; quis after nē is the regular indefinite “anyone.” invidēre normally governs a dative, with the target understood from context. Its meaning includes malicious envy and the culturally familiar “evil eye,” more than neutral admiration.
After sciat, tantum … esse bāsiōrum is indirect statement. tantum is neuter singular quantity, and bāsiōrum is partitive genitive: literally, “that there is so much of kisses.” The potential observer need not know the exact number; merely knowing its magnitude is dangerous. The final genitive echoes the earlier bookkeeping while refusing a count.
Literal translation
Let us live, my Lesbia, and let us love, and let us value all the rumors of rather stern old men at one as. Suns can set and return; for us, when once the brief light has set, one everlasting night must be slept. Give me a thousand kisses, then a hundred, then another thousand, then a second hundred, then continuously another thousand, then a hundred. Then, when we have made many thousands, we shall muddle those up so that we do not know, or so that no malicious person can envy us, when he knows there to be so much of kisses.
Idiomatic translation
Let us live, my Lesbia, and love. Let us value all the gossip of grim old men at a penny. Suns may set and rise again; once our short daylight has gone down, we must sleep one unending night. Give me a thousand kisses, then a hundred, then another thousand, another hundred, then another thousand without stopping, then a hundred more. When we have made many thousands, we shall mix up the count so that even we do not know it—and so that no spiteful onlooker can curse our happiness by knowing how many kisses there are.
Common Mistakes
1. Translating the opening subjunctives as statements.
❌ Vīvimus et amāmus.
‘We live and love’ is indicative; it removes Catullus's invitation.
✅ Vīvāmus atque amēmus.
Let us live and let us love.
2. Making nobis the subject of dormienda.
❌ Nōs nox perpetua dormienda sumus.
Incorrect: nos cannot replace the dative agent nobis, and singular nox requires est.
✅ Nōbīs nox perpetua dormienda est.
An everlasting night must be slept by us.
3. Ignoring the value genitive and translating only the gist.
❌ Rūmōrēs ūnīus as aestimēmus.
Incorrect: the value phrase requires genitive assis, not the nominative/accusative form as.
✅ Rūmōrēs ūnīus assis aestimēmus.
Let us value the rumors at one as.
4. Reading fecerimus automatically as a perfect subjunctive.
❌ Cum mīlia multa fēcerō, conturbābimus illa.
Incorrect person: singular fecero conflicts with the lovers' plural action in conturbabimus.
✅ Cum mīlia multa fēcerīmus, conturbābimus illa.
When we have made many thousands, we shall muddle them up.
Key Takeaways
The poem argues through grammatical contrasts: shared subjunctives choose a life, the value genitive dismisses public judgment, recurring infinitives describe the sun's cycle, and the gerundive marks the one night humans cannot escape. Imperatives and numbers then accelerate until future and purpose clauses deliberately destroy the count. A smooth “love while you can” paraphrase captures the theme, but only the Latin forms show how Catullus makes that conclusion feel inevitable.
