Kouros is the modern term given to free-standing ancient Greek sculptures that first appear in the Archaic period in Greece and represent nude male youths. In Ancient Greek kouros means "youth, boy, especially of noble rank". Although Kouroi have been found in many ancient Greek territories, they were especially prominent in Attica and Boiotia. The term kouros was first proposed for what were previously thought to be depictions of Apollo by V.I. Leonardos in 1895 in relation to the youth from Keratea, and adopted by Henri Lechat as a generic term for the standing male figure in 1904. Such statues are found across the Greek-speaking world; the preponderance of these were found in sanctuaries of Apollo with more than one hundred from the sanctuary of Apollo Ptoion, Boeotia, alone.[5] These free-standing sculptures were typically marble, but the form is also rendered in limestone, wood, bronze, ivory and terracotta. They are typically life-sized, though early colossal examples are up to 3 meters tall. Source : Wikipedia

Οι Κούροι (ενικός ο Κούρος), -οι γυναικείες μορφές ονομάζονται αντίστοιχα Κόρες- είναι η ονομασία των μεγάλων διαστάσεων μαρμάρινων αγαλμάτων ανδρικής μορφής, τα οποία μετά την μέση αρχαϊκή περίοδο 580 π.Χ. δεσπόζουν στην ελληνική τέχνη. Οι Κούροι είναι γυμνοί, ενώ οι κόρες είναι ντυμένες, όπως η Πεπλοφόρος κόρη. Τους Κούρους μπορεί κανείς να τους γνωρίσει και να τους μελετήσει κυρίως στο Αρχαιολογικό Μουσείο Αθηνών και τις Κόρες στο Μουσείο Ακρόπολης.
