Twilight

Twilight is the time between dawn and sunrise, and the time between sunset and dusk. Sunlight scattered in the upper atmosphere illuminates the lower atmosphere, and the surface of the Earth is not completely lit or completely dark. The sun itself is not actually visible because it is below the horizon. Due to the unusual, romantic quality of the ambient light at this time, twilight has long been popular with photographers and painters, who refer to it as the "blue hour", after the French expression l'heure bleue.

Twilight is technically defined as the portion of the day during which it is possible to conduct outdoor activities without the aid of artificial light, beginning in the morning and ending in the evening. The period of daylight (between sunrise and sunset) occurs within the period of twilight.

Ovidius

Publius Ovidius Naso (20 March 43 BC – AD 17 or 18) was a Roman poet known as Ovid to the English-speaking world, who wrote about love, seduction, and mythologic transformation. He is considered a master of the elegiac couplet, and is traditionally ranked alongside Virgil and Horace as one of the three canonic poets of Latin literature. His poetry, much imitated during Late Antiquity and the Middle Ages, decisively influenced European art and literature.

The Elegiac couplet is the metre of most of Ovid's poems: the Amores — Ars Amatoria, Remedia Amoris — are didactic long poems; the Fasti, about the Roman calendar; the Medicamina Faciei Femineae, about cosmetics; fictional letters from mythologic heroines, the Heroides or Epistulae Heroidum; and all of the works written in exile (five Tristia books, four Epistulae ex Ponto books, and "Ibis", a long curse-poem. The two, extant fragments of the tragedy Medea are in iambic trimeter and anapest, respectively; the Metamorphoses is in dactylic hexameter; the metre of the Aeneid, by Virgil and of the Odyssey and the Iliad, by Homer.
