Tenses in narrative: the historic present
At Β2 you made tenses agree. At Γ1 you choose them: present to make the past vivid, imperfect for the backdrop, aorist for the event.

The historic present
Greek switches to the present in the middle of a past narrative to put the reader on the spot: «Περπατούσα στον δρόμο, και ξαφνικά βλέπω τον Νίκο.» This is not a sequence-of-tenses error — it is an effect, extremely common in speech and journalism.
- Το 1453 πέφτει η Κωνσταντινούπολη.In 1453 Constantinople falls.
- Περπατούσα στον δρόμο και ξαφνικά βλέπω τον Νίκο.I was walking down the street and suddenly I see Nikos.
- Ο υπουργός φτάνει στην Αθήνα και ανακοινώνει τα μέτρα.The minister arrives in Athens and announces the measures.
Background and foreground
In narrative, the imperfect lays down the setting and lasting states; the aorist moves the action forward. Swapping one for the other does not make the sentence wrong — it moves what the reader perceives as the main event.

Често задавани въпроси
Why does a past narrative switch to the present in Greek?
It is the historic present, a stylistic effect that puts the reader on the spot: «Το 1453 πέφτει η Κωνσταντινούπολη» (in 1453 Constantinople falls). It is not a sequence-of-tenses error.
Imperfect or aorist in a Greek narrative?
The imperfect lays down the setting and lasting states; the aorist moves the action forward: «Περπατούσα στον δρόμο και ξαφνικά είδα τον Νίκο» (I was walking down the street and suddenly saw Nikos). Swapping them is not wrong — it shifts what the reader takes as the main event.
Is the historic present acceptable in writing?
Yes: it is very common in journalism and historical narration — «Ο υπουργός φτάνει στην Αθήνα και ανακοινώνει τα μέτρα» (the minister arrives in Athens and announces the measures) — as long as you do not alternate with the past at random in the same paragraph.
