day-star
day-star (dā"star`) , noun
1.
The morning star; the star which ushers in the day; -- usually the planet Venus, when seen before and just after sunrise.
A dark place, until the day dawn, and the day-star arise in your hearts.
2.
The sun, as the orb of day. [Poetic]
So sinks the day-star in the ocean bed,
And yet anon repairs his drooping head,
And tricks his beams, and with new-spangled ore
Flames in the forehead of the morning sky.
