English: Image of the fresco, "Ladies in Blue", from the Palace of Knossos on the island of Crete. It depicts women with hairstyles similar to the modern ponytail and has been dated to as far back as 1600-1430BCE. Fragments of this frescoe was discovered by Sir Arthur John Evans at the start of the 20th century. It was then recreated by Swiss artist and archaeologist Émile Gilliéron. However, the validity of his reconstructions has long been debated. The fragments are preserved in the Archaeological Museum of Heraklion, Crete.
