The Morning Star

Poul Anderson's The Day Of Their Return begins by quoting JOB, iv, 12-16, which ends: "...I heard a voice..." so what does the voice say? See here.

The evening star is also the morning star:

"...the morning star shone there, the planet of the First Chosen."
-Poul Anderson, The Day Of Their Return IN Anderson, Captain Flandry: Defender Of The Terran Empire (Riverdale, NY, 2010), pp. 74-238 AT 1, p. 75.

"He/they went up the mountain to the Arena. Above them paled Dido, the morning star."
- op. cit., p. 76.

In the Virgilian System, the third planet, Dido, has native inhabitants and the fourth planet, Aeneas, has been colonized by human beings. We have read about:

Peter Berg from Aeneas;
Hugh McCormac riding with his sons on Aeneas;
Dominic Flandry and Kathryn McCormac on Dido.

We are about to read an entire novel set on Aeneas where Dido is both morning and evening star.
