The moon regularly seems to disappear and then return. The waxing (increasing) and waning (decrease) in the Moon’s appearance to primitive peoples seemed to be similar to our own life and death cycle – and perhaps, to our rebirth.

Stories which associate the moon with the origin of death are found especially around the Pacific region. According to J. G. Frazer’s The Belief in Immortality and The Worship of the Dead, in Fiji, it is said that the moon suggested that mankind should return as he did. But the rat god, Ra Kalavo, would not permit this, insisting that men should die like rats.

In Australia, the Wotjobaluk aborigines say that the moon used to revive the dead until an old man said that this should stop.

The Cham have it that the goddess of good luck used to revive the dead but the sky-god sent her to the moon so she could not do this any more.

A waning Moon is sometimes considered an unlucky time for a marriage or birth.

In South Africa, it is considered unlucky to start a journey or begin any important work during the last quarter of the Moon.

In Cornwall, if a boy was born during a waning Moon, they said that the next birth would be a girl.

In Wales, if you moved from one house to another during the Crescent Moon you would have more than enough prosperity in your life.

We know now that the lunar phase of the moon is the appearance of the illuminated (lit) portion of the Moon as seen by an observer, usually on Earth. The lunar phases change cyclically as the Moon orbits the Earth, according to the changing relative positions of the Earth, Moon, and Sun.

One half of the lunar surface is always illuminated by the Sun (except during lunar eclipses), and hence is bright, but the portion of the illuminated hemisphere that is visible to an observer can vary from about 100% (full moon) to 0% (new moon).

There are names for the phases
