Delphine de Cool (1830 - circa 1921) was born in Limoges and studied under her father Paul Fortin. She married the painter and sculptor Arnould de Cool and her son Gabriel, born in 1854, also became a painter. Better known for her work on canvas she may have worked on this vase as a special commission.
In Greek mythology, Andromeda was the daughter of Cepheus and Cassiopeia, king and queen of the kingdom Aethiopia. Her mother Cassiopeia boasted that her daughter was more beautiful than the Nereids, the nymph-daughters of the sea god Nereus and often seen accompanying Poseidon. To punish the queen for her arrogance, Poseidon, brother to Zeus and god of the sea, sent a sea monster named Cetus to ravage the coast of Aethiopia. The desperate king consulted the Oracle of Apollo, who announced that no respite would be found until the king sacrificed his daughter, Andromeda, to the monster. Stripped naked, she was chained to a rock on the coast. Perseus was returning from having slain the Gorgon Medusa and happened upon the chained Andromeda. He approached Cetus while invisible (for he was wearing Hades's helm), and killed the sea monster. He set Andromeda free, and subsequently married her.
