Aristarchus of SamosAristarchus of Samos (ˌærəˈstɑrkəs; Ἀρίσταρχος ὁ Σάμιος, Aristarkhos ho Samios; 310-230 BCE) was an ancient Greek astronomer and mathematician who presented the first known heliocentric model that placed the Sun at the center of the known universe, with the Earth revolving around the Sun once a year and rotating about its axis once a day. He was a student of Strato of Lampsacus, who was the third head of the Peripatetic School in Greece. According to Ptolemy, during Aristarchus' time there, he observed the summer solstice of 280 BCE.
Cato the ElderMarcus Porcius Cato (ˈkeɪtoʊ, ; 234–149 BC), also known as Cato the Censor (Censorius), the Elder and the Wise, was a Roman soldier, senator, and historian known for his conservatism and opposition to Hellenization. He was the first to write history in Latin with his Origines, a now fragmentary work on the history of Rome. His work De agri cultura, a rambling work on agriculture, farming, rituals, and recipes, is the oldest extant prose written in the Latin language.
AchillesIn Greek mythology, Achilles (əˈkɪliːz ) or Achilleus (Ἀχιλλεύς) was a hero of the Trojan War, the greatest of all the Greek warriors, and the central character of Homer's Iliad. He was the son of the Nereid Thetis and Peleus, king of Phthia. Achilles' most notable feat during the Trojan War was the slaying of the Trojan prince Hector outside the gates of Troy. Although the death of Achilles is not presented in the Iliad, other sources concur that he was killed near the end of the Trojan War by Paris, who shot him with an arrow.
CleopatraCleopatra VII Thea Philopator (, lit. Cleopatra "father-loving goddess"; 70/69 BC - 10 August 30 BC) was Queen of the Ptolemaic Kingdom of Egypt from 51 to 30 BC, and its last active ruler. A member of the Ptolemaic dynasty, she was a descendant of its founder Ptolemy I Soter, a Macedonian Greek general and companion of Alexander the Great. After the death of Cleopatra, Egypt became a province of the Roman Empire, marking the end of the last Hellenistic period state in the Mediterranean and of the age that had lasted since the reign of Alexander (336–323 BC).
