Joachimsen, Kristin, (2022). "Yehudite Imaginations of King Darius and His Officials: Views from the Province beyond the River", in: Religions, Vol. 13, Issue 3: "Hag 2:18 describes how the temple’s foundations were laid in the second year of Darius, but neither Haggai nor Zechariah 1–8 mentions the completion of the temple. For that reason, many have concluded that these writings must be dated before 515 BCE (Ristau 2016, p. 119)."
