#Athens
- Academus — A legendary hero from ancient Attic mythology, whose primary historical and cultural significance derives from his connection to the origins of Western education. Academos owned an estate and a sacred olive grove (located northwest of Athens) where, according to myth, he helped the Dioscuri rescue Helen. This sacred grove, named 'Hekademeia' or 'Akademeia' in his honor, was later chosen by the philosopher Plato in 387 BC as the site for his famous school, transforming the hero's name into the universal etymological root for 'academy' and 'academic'.
- Academus — The Latinized variant of the name of the ancient Attic hero Academos, primarily used in Western scholarly literature, philosophical treatises written in Latin, and European classicist poetry. The character is the famous mythological owner of the olive grove near Athens, the sacred space within which Plato established his philosophical school. The name represents the direct etymological foundation from which modern neologisms regarding institutions of higher learning and research developed.
- The Acropolis — The proper name of the most famous and representative acropolis of the ancient world, situated on a flat rock dominating the city of Athens, Greece. This monumental complex of exceptional universal architectural value houses masterpieces of the Classical era (5th century BC, coordinated by Pericles and Phidias), including the Parthenon temple, the Erechtheion with its caryatids, the temple of Athena Nike, and the Propylaea.
- Actaeus — A character in Greek mythology, structurally recognized as the legendary first king of Attica (the historical region surrounding Athens), prior to the reign of Cecrops. According to ancient traditions described by Pausanias, he named the land 'Actaea' after himself; later, his daughter, Agraulos, married Cecrops, thus passing down the royal succession. His name is deeply linked to the autochthonous origins and first territorial settlements in the Hellenic space.
- Acteu — A current Romanian graphic and phonetic variant for 'Actaeus'; a character in Greek mythology recognized as the legendary first king of Attica (the region surrounding Athens) prior to Cecrops. He is considered a primordial autochthonous ruler, born directly from the earth, who gave the initial name to the region ('Actaea') and consolidated the first territorial settlements in the Hellenic space before written history was recorded in ancient documents.
- Aegeus — Mythical king of Athens, son of Pandion II and father of the hero Theseus, recognized in Hellenic legends for founding early Athenian power structures. His name is permanently linked to the Aegean Sea, into whose waves he threw himself from the cliffs of the Acropolis due to a tragic misunderstanding, erroneously believing his son was killed by the Cretan Minotaur because the returning ship carried black sails.
- Aegos — A shortened form or toponymic reference associated with Aegospotami (Goat's River), an ancient river and settlement in the Thracian Chersonese, famous as the site of the decisive naval battle in 405 BC where the Spartan fleet led by Lysander destroyed Athenian forces, ending the Peloponnesian War. In a secondary mythological context, the name alludes to protective elements linked to Zeus or the goat-nymph Amalthea.
- Agathon — An ancient Greek tragic poet from Athens, a contemporary of Socrates and Euripides, famously known as the main character and host in Plato's celebrated dialogue, the 'Symposium'. His work, of which only very few fragments survive, introduced structural innovations into Hellenic tragedy, such as utilizing entirely fictional characters and plots instead of traditional mythology, as well as composing musical interludes independent of the play's main plot.
- Agora — The central public space and marketplace in ancient Greek city-states (poleis), serving as the hub of political, commercial, administrative, and religious life. In modern sociology and political science, it is used metaphorically to denote the open public sphere or forum for democratic debate.
- Agraulos — A term of Greek origin historically used as an epithet or proper name relating to outdoor life, fields, or the wilderness. In Greek mythology, it directly references Agraulos (or Aglaurus), one of the daughters of Cecrops, the mythical first king of Athens, serving as a central figure in the military initiation oaths taken by young ephebes.
- Alcibiades — Alcibiades (c. 450–404 BCE), a famous Athenian politician, orator, and general during the Peloponnesian War, renowned for his brilliant intelligence, exceptional charisma, but also for his opportunistic and volatile character. A disciple of Socrates and relative of Pericles, he played a crucial structural role in ancient Greek history, successively changing sides to support Athens, Sparta, and Persia depending on his political interests and survival.
- Amphictyon — A character in Greek mythology, the son of Deucalion and Pyrrha, and a legendary king of Athens after deposing Cranaus. In ancient history, he is considered the founding eponym of the Amphictyonic League (Amphictyonia), an early religious and political confederation of Hellenic tribes organized around the sanctuaries of Delphi and Thermopylae to protect sacred sites and maintain tribal peace.
- Anaxagoras — Anaxagoras of Clazomenae (c. 500 – 428 BC); a famous presocratic Greek philosopher who introduced into philosophical thought the structural notion of 'Nous' (the universal Mind or Reason) as an ordering force governing the primordial matter made of 'homeomeries' (eternal seeds of all things). He is historically recognized for moving the center of philosophy to Athens and for his rational explanations regarding eclipses and celestial phenomena.
- Antisthenes — An ancient Greek philosopher from Athens (c. 445 – 365 BC), a direct disciple of Socrates and considered the founder of the Cynic school of philosophy. In the evolution of Western thought, Antisthenes laid the foundations of Cynic asceticism, arguing that virtue is the sole path to happiness (eudaimonia) and that it relies on self-control, the rejection of artificial social conventions, luxury, and material pleasures, directly influencing Diogenes of Sinope.
- Archeptolemus — The Latinized name of Archeptolemos, a mythological character mentioned in Homer's Iliad as the son of Iphitus and the brave charioteer of the Trojan hero Hector. He demonstrated remarkable structural loyalty on the Trojan battlefield until he was killed by an arrow from Teucer, which was aimed at Hector. The name also refers to a real political figure from ancient Athens (5th century BC), son of Hippodamus, involved in oligarchic movements and later executed for treason.
- Arrephorae — The name borne by the young noble girls in ancient Athens (aged between 7 and 11) who lived temporarily on the Acropolis to serve the goddess Athena.

- Areopagus — The supreme judicial council of ancient Athens, originally composed of former high-ranking magistrates (archons), which met on the hill dedicated to the god Ares to deliberate on state crimes and constitutional matters.

- Areopagite — A member of the Areopagus, the highest judicial court and aristocratic council in ancient Athens, which historically met on the rock dedicated to the god Ares. In a Christian religious and theological sense, the term refers directly to Saint Dionysius the Areopagite, the Athenian judge converted by Saint Paul the Apostle, to whom the celebrated mystical writings of the Areopagitic corpus were structurally attributed. In an extended or literary sense, it denotes a judge of unquestionable moral and professional authority or a member of a supreme court.
