"The summer day is closed, the sun is set Well they have done their office, those bright hours, The latest of whose tram goes softly out In the red west."
"Dim eclipse, disastrous twilight."

Twilight is daylight illumination produced by diffuse sky radiation when the Sun is below the horizon as sunlight from the upper atmosphere is scattered in a way that illuminates both the Earth's lower atmosphere and also the Earth's surface. Twilight also may be any period when this illumination occurs, including dawn and dusk.
"The summer day is closed, the sun is set Well they have done their office, those bright hours, The latest of whose tram goes softly out In the red west."
"As pensive evening deepens into night."
"Fair Venus shines Even in the eve of day, with sweetest beam Propitious shines, and shakes a trembling flood Of softened radiance from her dewy locks."
"The lengthening shadows wait The first pale stars of twilight."
"The twilight is sad and cloudy, The wind blows wild and free, And like the wings of sear-birds Hash the white caps of the sea."
"Sweet shadows of twilight how calm their repose, While the dewdrops fall soft in the breast of the rose! How blest to the toiler his hour of release When the vesper is heard with its whisper of peace!"
