Wreath History

 A wreath is a ring made of flowers, leaves, and sometimes fruits,
used as an ornament, hanging on a wall or door, or resting on a table.
 
A wreath woven with flowers is used as a garment
in some zones of Polynesia around the head, as a diadem;
sometimes referred to as a lei.

By extension the name wreath applies in art to the carved
or modelled representation of this ring.

In Greek mythology Apollo is represented wearing a laurel-wreath,
and wreaths were awarded to victors,
both in athletic competitions and poetic meets under his care.

Dionysus is crowned with a wreath of ivy (in his wild and dangerous aspect),
or with the vine, as the inventor of civilizing wine. 

The god Dionysus is occasionally confused with one of several historical figures named Dionysius, a theophoric name that simply means "[servant] of Dionysus.

Dionysus (or Dionysos; also known as Bacchus in Roman mythology and associated with the Italic Liber),
the Thracian god of wine, represents not only the intoxicating power of wine,
but also its social and beneficent influences. 

He is viewed as the promoter of civilization, a lawgiver, and lover of peace — as well as the patron deity of both agriculture and the theater.
