who initiated the rebuilding of the second temple
Second Temple The accession of Cyrus the Great of the Persian Empire in 559 BCE made the re-establishment of the city of Jerusalem and the rebuilding of the Temple possible.[1][2] According to the closing verses of the second book of Chronicles and the books of Ezra and Nehemiah, when the Jewish exiles returned to Jerusalem following a decree from Cyrus the Great (Ezra 1:1–4, 2 Chron 36:22–23), construction started at the original site of Solomon's Temple. After a relatively brief halt due to opposition from peoples who had filled the vacuum during the Jewish captivity (Ezra 4), work resumed c. 521 BCE under Darius the Great (Ezra 5) and was completed during the sixth year of his reign (c. 516 BCE), with the temple dedication taking place the following year.[citation needed]
Temple of Jupiter Optimus Maximus Much of what is known of the first Temple of Jupiter is from later Roman tradition. Lucius Tarquinius Priscus vowed this temple while battling with the Sabines and, according to Dionysius of Halicarnassus, began the terracing necessary to support the foundations of the temple.[8] Modern coring on the Capitoline has confirmed the extensive work needed just to create a level building site.[9] According to Dionysius of Halicarnassus and Livy, the foundations and most of the superstructure of the temple were completed by Lucius Tarquinius Superbus, the last King of Rome.[10]
