Horae.

 The Horae (Ὥραι) were goddesses of the seasons in ancient Greece. Their parents were Zeus (Ζεύς) and Themis (Θέμιδος). Or Helios (Ἠέλιος) and Selene (Σελήνη). 

Also, the Horae kept order in nature.

In different periods there were different numbers of the Horae.

They harnessed the horses of  Helios. The Horae guarded the gates of Olympus. The goddesses met with Aphrodite (Ἀφροδίτη) and Pandora (Πανδώρα). 

Thallo (Θαλλώ) was the goddess of spring and protector of youth.

Auxo (Αὐξώ) was Horae, the protector of plants.

Carpo (Καρπώ) was one who brought food.

Dike (Δίκη) was the goddess of justice and moral.

Eunomia (Εὐνομία) was the Horae of legislation and law.

Eirene (Εἰρήνη) was the Horae and goddess of peace and silence. 

Ancient writers wrote many myths and legends about the Horae. There are different paintings and sculptures the describe them.

Pandora's box.

 Pandora (Πανδώρα,) was created by Hephaestus. She was the first human woman. Hephaestus created her under the instructions of Zeus. Her name means "all-giving".

Pandora had relationships with gods and goddesses, such as: Athena, Hermes, and Aphrodite. They gave her different gifts.

Epimetheus became Pandora's husband. He was a titan. His brothers were Prometheus, Atlas, and Menoetius.

One day Pandora knew about box or jar pithos (πίθος) in a house. It was closed. But Pandora was very curious.

She opened this jar. There were death, sickness, and many other evils which appeared in the world. When Pandora closed the box just hope left there.

Pandora's box became an idiom. "Open a Pandora's box" meaning do something negative or problematic.

Many artists painted different paintings about this myth. Sculptors created statues of characters of this legend.
