This is a copy of a fresco painting from the Minoan era (1). It’s called “the mural painting of Spring”. The fresco painting was found at the volcanic (2) island of Thera, present-day Santorini.

(1) The Minoan civilization was a Bronze Age Aegean civilization on the island of Crete and other Aegean Islands, flourishing from c. 3000 BC to c. 1450 BC.
2) The volcano on Thera erupted in mid-second millennium BCE and destroyed the Minoan city of Akrotiri. Akrotiri was entombed by pumice and ash and since its rediscovery has been referred to as the Minoan Pompeii. The frescoes on Akrotiri were preserved by the blanketing volcanic ash.
