Reappear

Metal birds come and go, deliver and take people and goods, disappear and reappear behind the symmetrical artificial mountains.

Halley is the comet that proved correct Edmund Halley's prediction that it would reappear.

Those too, whom late we scattered through the town, / tricked in the darkness, reappear once more. / At once the falsehood of our guise is known, / the shields, the lying arms, the speech of different tone.

Stefan didn’t reappear.

Halley's Comet is the best known because it can be seen with the naked eye as it passes by periodically. It was first noticed more than 2,000 years ago. Astronomers have observed and documented its appearances, which has helped them understand comets in general. The comet was named after 17th-century British astronomer Edmond Halley, who computed the rate of its movement from his 1682 observations and predicted that it would reappear in 1758, long after his death.

After the slumber of the year / The woodland violets re-appear, / All things revive in field or grove, […]

Day after day it reappears / Night after night my heartbeat shows the fear / Ghosts appear and fade away
