- A-type stars are among the more common naked eye stars, and are white or bluish-white. They have strong hydrogen lines, at a maximum by A0, and also lines of ionized metals (Fe II, Mg II, Si II) at a maximum at A5. The presence of Ca II lines is notably strengthening by this point. About 1 in 160 (0.625%) of the main-sequence stars in the solar neighborhood are A-type stars, which includes 9 stars within 15 parsecs.

The one apocalypse of the New Testament canon, Revelation was written in Koine Greek in the first century AD by a prophet named John on the island of Patmos. Opening with letters to seven churches of Asia Minor, it unfolds in visions of heavenly worship, seals, trumpets, and plagues, culminating in the fall of Babylon and the descent of the new Jerusalem.
