The Minoans were known for their seafaring skills, and their ships were some of the most advanced of their time. They established trade routes with other civilizations, such as Egypt and the Mycenaean Greeks, and their artifacts have been found in places as far away as Egypt, Turkey, and Cyprus.Some historians have even suggested that the Minoans may have had contact with civilizations in the Americas.

Les anciens Grecs sont connus pour leurs grandes réalisations dans les domaines de la philosophie, de l'art, des sciences, et plus encore. Mais saviez-vous qu'ils ont également eu une présence importante dans le sud de la France ?
À partir du VIe siècle avant notre ère, des colonies grecques ont été établies le long de la côte méditerranéenne du sud de la France, principalement par les Phocéens, les Massaliotes et les Rhodiens. Ces colonies ont servi de postes commerciaux importants, reliant le monde grec à d'autres cultures et marchés dans la Méditerranée occidentale.
