In Metamorphoses 10, Orpheus has persuaded the rulers of the underworld to release Eurydice on one condition: he must not look back until they have left the world below. Ovid narrates the rule, the difficult ascent, the glance, and its immediate consequence in ten hexameter lines. The grammar makes the disaster feel simultaneously preventable and inevitable: a future condition opens a narrow path to success, dense modifiers slow the climb, and then perfect verbs make the reversal instantaneous.
This is literary Classical Latin. Its tense system, fear clause, gerund, and participles are productive constructions, but the separation of tightly connected words and the accumulation of verbless adjectives are distinctly poetic. The aim is therefore to read from endings and dependencies first, then ask how Ovid turns those dependencies into pacing.
The complete passage
The text is Ovid, Metamorphoses 10.50–59. It is reproduced without teaching macrons, as an attributed quotation. Punctuation and capitalization are editorial.
Hanc simul et legem Rhodopeius accipit heros,
ne flectat retro sua lumina, donec Avernas
exierit valles; aut inrita dona futura.
Carpitur acclivis per muta silentia trames,
arduus, obscurus, caligine densus opaca.
Nec procul afuerunt telluris margine summae:
hic, ne deficeret, metuens avidusque videndi,
flexit amans oculos; et protinus illa relapsa est,
bracchiaque intendens prendique et prendere certans
nil nisi cedentes infelix arripit auras.
The passage is in dactylic hexameter. Syntax runs repeatedly across line endings: donec waits until exierit in the next line; the subject trames follows its verb and adjective; and illa relapsa est follows the fatal glance with almost no connective delay. For the broader meter, see Dactylic Hexameter.
Receiving a person and a rule
Hanc simul et legem Rhodopeius accipit heros.
At the same time the Rhodopean hero receives her and this condition. (Ovid, Metamorphoses 10.50)
The finite skeleton is hērōs accipit, “the hero receives.” Rhodopēius agrees with hērōs and identifies Orpheus by the Thracian mountain Rhodope. The two accusative objects are hanc, “her,” meaning Eurydice, and legem, “condition” or “rule.” et joins those objects; simul says that woman and rule come together. Orpheus cannot accept one without the other.
English naturally repeats “receives”: “he receives her and accepts the condition.” Latin lets accipit govern both, although its nuance shifts from receiving a person to accepting terms. That zeugma is not a special grammatical license; one verb can govern coordinated objects. Its literary effect matters: Eurydice enters the syntax already bound to the prohibition.
The rule as a future boundary
Ne flectat retro sua lumina, donec Avernas exierit valles.
He must not turn his eyes backward until he has left the valleys of Avernus. (Ovid, Metamorphoses 10.51–52)
Here nē flectat states the content of legem: “the condition that he not turn.” The present subjunctive is natural after a noun whose content is being specified, and it also has prohibitive force. sua lūmina means his own eyes; reflexive sua points back to Orpheus. retrō is an adverb, not an adjective modifying the eyes.
The time clause dōnec ... exierit sets the endpoint. Morphologically exierit can be either future perfect indicative or perfect subjunctive, but here the perfect subjunctive is the stronger analysis: the whole rule is reported as the content of legem, and the endpoint after dōnec is anticipated rather than narrated as a fact. Its temporal force is still future-anterior—leaving must be complete before looking back becomes permissible. Avernās vallēs is accusative plural and the direct object of transitive exīre in poetic usage. Prose often uses ex + ablative, but an accusative object with compound verbs of motion is well established, especially in poetry.
The diagnostic is temporal logic. The departure must be complete before looking back becomes safe. English often uses a present perfect after “until,” whereas Latin can mark that future completion explicitly.
Aut inrita dona futura.
Otherwise the gifts were destined to become void. (Ovid, Metamorphoses 10.52)
This is compressed indirect discourse: dōna inrita futūra [esse], “that the gifts would become void,” with esse omitted from the future infinitive. Neuter plural dōna is visibly identical in nominative and accusative, but here it is the accusative subject of futūra esse; predicate inrita and future participle futūra agree with it. aut has the force “or else.” The “gifts” are Eurydice's release, and futūra cannot agree with feminine vallēs.
Ovid therefore frames the ascent as a contract with a future deadline. The rule does not merely forbid curiosity; it makes the gift's validity depend on the timing of Orpheus's gaze.
A road stretched by modifiers
Carpitur acclivis per muta silentia trames.
The upward-sloping path is traversed through mute silence. (Ovid, Metamorphoses 10.53)
Nominative trāmes is the delayed subject of passive carpitur, literally “is plucked” and here “is covered little by little” or “traversed.” Nominative acclīvis agrees with trames. per mūta silentia is deliberately intense: plural silentia evokes expanses or repeated zones of silence, while mūta makes the silence itself speechless.
The passive suppresses the walkers. Instead of “they climb,” the road is consumed under their steps. This shifts attention from agents to arduous progress and keeps Orpheus and Eurydice unnamed during the ascent.
Arduus, obscurus, caligine densus opaca.
Steep, dark, and dense with murky mist. (Ovid, Metamorphoses 10.54)
These four adjectives continue to describe trāmes across the line break: arduus, obscūrus, and dēnsus are masculine nominative singular. opācā agrees with ablative cālīgine, governed by densus, “dense with.” There is no new finite verb.
English readers often mistake a line boundary for a sentence boundary. Endings defeat that temptation: the masculine nominatives can modify trames, while ablative caligine opaca cannot be a new subject. The delayed descriptive pileup makes the line itself labor uphill.
The threshold almost reached
Nec procul afuerunt telluris margine summae.
And they were not far from the upper boundary of the earth. (Ovid, Metamorphoses 10.55)
The understood subject of plural āfuērunt is Orpheus and Eurydice. procul abesse means “be far away”; ablative margine supplies the point of separation without an expressed ā. Genitive tellūris summae is best taken as “of the uppermost earth”: summae agrees with telluris, not margine.
Perfect afuerunt views the state from the narrator's retrospective vantage. They had come close to the boundary. Placing success within reach makes the next clause tragic rather than random.
Fear reverses the English signal
Hic, ne deficeret, metuens avidusque videndi, flexit amans oculos.
Here, fearing that she might fail, and eager to see her, the lover turned his eyes. (Ovid, Metamorphoses 10.56–57)
The main verb is flexit; nominative participle metuēns and adjectives avidus and substantival amāns, “the lover,” all describe Orpheus. Genitive gerund videndī depends on avidus, “eager to see.” Context supplies Eurydice as the unexpressed object of seeing.
The fear clause is nē dēficeret. After a verb or expression of fearing, Latin nē introduces the event feared: Orpheus fears that she may fail, falter, or fall away. English “lest” preserves the construction, but ordinary English uses positive “that,” so learners often reverse it. The imperfect subjunctive places the feared failure within past narrative time.
Two motives converge before the verb: concern for Eurydice and desire to see her. Ovid does not reduce the glance to mere disobedience. amans stands directly beside oculōs and makes love the agent of the fatal motion.
Consequence at once
Et protinus illa relapsa est.
And immediately she slipped back. (Ovid, Metamorphoses 10.57)
Adverb prōtinus, “immediately,” allows no recovery. relāpsa est is the perfect of deponent relābor; the participle is feminine because illa is Eurydice. Although the form resembles a passive, the deponent has active meaning: “she slipped back.”
The short clause follows the glance without explanation. Rule and consequence had already been joined by the future periphrastic; now the perfect realizes that threatened future in a single beat.
Bracchiaque intendens prendique et prendere certans nil nisi cedentes infelix arripit auras.
Stretching out her arms and struggling both to be grasped and to grasp, the unhappy woman catches nothing but yielding air. (Ovid, Metamorphoses 10.58–59)
Feminine nominatives intendēns, certāns, and īnfēlīx describe Eurydice. bracchia is the object of intendens. The coordinated infinitives are poignantly reciprocal: passive prendī, “to be grasped,” and active prendere, “to grasp.” Both depend on certans. Present arripit is a vivid historical present after the perfect relapsa est.
The object of arripit is nil nisi ... aurās, “nothing except ... air.” cēdentēs means the air gives way as she tries to clutch it. Grammar turns the separation into failed reciprocity: each infinitive needs another person, but the only finite act left to Eurydice meets no body.
Literal translation
The Rhodopean hero receives her and at the same time this condition: that he not turn his eyes backward until he has left the valleys of Avernus; otherwise the gifts are going to be void. The rising path is traversed through mute silences, steep, dark, dense with murky mist. They were not far from the boundary of the upper earth. Here, fearing that she might fail and eager to see, the lover turned his eyes; immediately she slipped back. Stretching out her arms and struggling both to be grasped and to grasp, the unhappy woman catches nothing except yielding air.
Idiomatic translation
Orpheus received Eurydice together with one condition: he must not look back until he had climbed completely out of the valley of Avernus, or the gift would be revoked. They made their way up the steep path through absolute silence, in darkness and thick mist. They were almost at the surface when Orpheus, afraid Eurydice was faltering and desperate to see her, looked back. At once she fell away. Reaching out and struggling both to catch him and be caught, she grasped only the air as it yielded through her hands.
Common Mistakes
1. Making the prospective perfect subjunctive a past event.
❌ Dōnec Avernās exierat vallēs, lūmina nōn flexit.
Incorrect analysis: exierit in Ovid's rule is not the pluperfect exierat, and the rule is prospective.
✅ Nē flectat lūmina, dōnec Avernās exierit vallēs.
He must not turn his eyes until he has left the valleys of Avernus.
2. Pairing futūra with vallēs.
❌ Avernae vallēs futūrae sunt.
Incorrect reconstruction: Ovid's futura is neuter plural and agrees with dona, not feminine valles.
✅ Dōna inrita futūra sunt.
The gifts are going to become void.
3. Reversing the fear clause.
❌ Metuit nē Eurydicē nōn dēficeret.
Incorrect: adding non would mean that he feared Eurydice might not falter, reversing the feared event.
✅ Metuit nē Eurydicē dēficeret.
He feared that Eurydice might falter.
4. Translating relapsa est as a passive.
❌ Eurydicē relāpsa est ab Orpheō.
Incorrect: relabor is deponent; relapsa est does not mean ‘was slipped by Orpheus.’
✅ Eurydicē prōtinus relāpsa est.
Eurydice immediately slipped back.
Key Takeaways
The passage's grammar draws a clean causal line. accipit binds Eurydice to a lēx; prospective dōnec ... exierit defines the safe endpoint; dōna ... futūra [esse] states the threatened result; passive carpitur and accumulated adjectives prolong the climb; nē dēficeret reveals loving fear at the threshold; then flexit and relāpsa est make act and consequence adjacent. Finally, prendī et prendere expresses a reciprocity that the plot has made impossible. A translation that merely says “Orpheus looked back and lost her” gets the event, but the Latin dependencies explain why Ovid's telling hurts.
