Note the Roman Civil War of 68 AD began with the revolts of Vindex and Galba in Spain.
The above coins of Vindex and Galba displays the wreath on the reverse with what has been described as a jewel at its apex. As I have described in previous posts this is likely a star or a solar eclipse. The end of the Julio-Claudian dynasty was a new beginning in Roman politics. Rome was founded during a solar eclipse and this symbolism is not lost with new emperors ascending to the throne.
The above coin was minted in Rome when Galba became emperor. The solar eclipse symbolism on the legionary standards was present with all 5 emperors of the civil war and culminated with the victory of Vespasian. Vespasian was not from Roman nobility and his ascension to the throne was respected in the traditional line of Roman theology, Romulus killing his brother Remus and founding the Flavian dynasty.
About 7 months after the destruction of the Second Jewish Temple this solar eclipse was seen almost equidistant from Rome and Jerusalem. Note the booty from the Jerusalem temple was on it's way to or in Rome at the time.
The 75 AD solar eclipse appeared as Vespasian started building the Flavian Amphitheater or the Colosseum. The work force consisted of Jewish captives and was financed with the treasures of the Second Temple. Please see my prior post with the coin of Agrippa II and the 75 AD solar eclipse.
