Spectaculo finito, amici per viam domum ambulant et de scaena loquuntur.

Spectaculo finito is an ablative absolute. Literally it’s “the show having been finished” or “with the show finished.” Latin often uses this construction to set the scene (time/circumstance) without making it the main clause.

Because an ablative absolute normally uses:

• a noun/pronoun in the ablative (spectaculo, “the show”)
• plus a participle or adjective also in the ablative agreeing with it (finito, “finished”)

It’s “absolute” because it’s grammatically separate from the main sentence.

Finito is the perfect passive participle of fīniō, fīnīre (“to finish/end”), here ablative singular neuter to match spectaculo (also ablative singular neuter).

Yes, post spectaculum = “after the show.”
The ablative absolute spectaculo finito is a bit more descriptive: “once the show was over / with the show having ended.” It can feel slightly more narrative than a simple prepositional phrase.

Amici is nominative plural of amicus (“friend”), so it’s the subject: “the friends.”
The verbs ambulant and loquuntur are 3rd person plural, matching amici.

Ambulant is present tense (3rd plural) of ambulō: “they walk / they are walking.”
In narratives, Latin often uses the present to make the scene vivid (like an “historical present”), though it can also just be a simple present depending on context.

Per takes the accusative case.
So via (nominative/ablative) becomes viam (accusative): “along the road / through the street.”

Domum is a special accusative form meaning “(to) home” with verbs of motion, often without a preposition.
So domum ambulant = “they walk home.”

Most commonly domum means “home” (toward home).
It can sometimes mean “to the house” in context, but the default learner-friendly sense is “home.”

Loquuntur is from loquor, which is a deponent verb: it looks passive in form but is active in meaning.
So loquuntur means “they speak/talk,” not “they are spoken.”

Loquor commonly takes:

• de + ablative for “talk about” → de scaena = “about the stage”
• or a dative for “speak to/with someone”

A direct accusative object is not the normal pattern for loquor in this meaning.

Scaena is ablative singular because it follows de, and de governs the ablative: de scaena = “about the stage / about the scene.”
