DiophantusDiophantus of Alexandria (born AD 200-214; died AD 284-298) was a Greek mathematician, who was the author of a series of books called Arithmetica, many of which are now lost. His texts deal with solving algebraic equations. Diophantine equations, Diophantine geometry, and Diophantine approximations are subareas of Number theory that are named after him. Diophantus coined the term παρισότης (parisotes) to refer to an approximate equality.
Apollonius of TyanaApollonius of Tyana (Ἀπολλώνιος; بلينس; अपालुन्यःc. 15 – c. 100 AD) was a first-century Greek philosopher and religious leader from the town of Tyana, Cappadocia in Roman Anatolia, who spent his life travelling and teaching in the Middle East, North Africa and South Asia. He is a central figure in Neopythagoreanism and was one of the most famous "miracle workers" of his day. His exceptional personality and his mystical way of life, which was regarded as exemplary, impressed his contemporaries and had a lasting cultural influence.
ArchytasArchytas (ˈɑrkɪtəs; Ἀρχύτας; 435/410–360/350 BC) was an Ancient Greek philosopher, mathematician, music theorist, astronomer, statesman, and strategist. He was a scientist affiliated with the Pythagorean school and famous for being the reputed founder of mathematical mechanics and a friend of Plato. Archytas was born in the Greek city of Taras (Tarentum), Magna Graecia, and was the son of either Mnesagoras or Hadees. For a while, he was taught by Philolaus, and taught mathematics to Eudoxus of Cnidus and to Eudoxus' student, Menaechmus.
AristoxenusAristoxenus of Tarentum (Ἀριστόξενος ὁ Ταραντῖνος; born 375, fl. 335 BC) was a Greek Peripatetic philosopher, and a pupil of Aristotle. Most of his writings, which dealt with philosophy, ethics and music, have been lost, but one musical treatise, Elements of Harmony (Greek: Ἁρμονικὰ στοιχεῖα; Latin: Elementa harmonica), survives incomplete, as well as some fragments concerning rhythm and meter. The Elements is the chief source of our knowledge of ancient Greek music.
Alcmaeon of CrotonAlcmaeon of Croton (ælkˈmiːɒn; Ἀλκμαίων ὁ Κροτωνιάτης, Alkmaiōn, gen.: Ἀλκμαίωνος; fl. 5th century BC) was an early Greek medical writer and philosopher-scientist. He has been described as one of the most eminent natural philosophers and medical theorists of antiquity and he has also been referred to as "a thinker of considerable originality and one of the greatest philosophers, naturalists, and neuroscientists of all time." His work in biology has been described as remarkable, and his originality made him likely a pioneer.
Musica universalisThe musica universalis (literally universal music), also called music of the spheres or harmony of the spheres, is a philosophical concept that regards proportions in the movements of celestial bodies – the Sun, Moon, and planets – as a form of music. The theory, originating in ancient Greece, was a tenet of Pythagoreanism, and was later developed by 16th-century astronomer Johannes Kepler. Kepler did not believe this "music" to be audible, but felt that it could nevertheless be heard by the soul.
Theon of SmyrnaTheon of Smyrna (Θέων ὁ Σμυρναῖος Theon ho Smyrnaios, gen. Θέωνος Theonos; fl. 100 CE) was a Greek philosopher and mathematician, whose works were strongly influenced by the Pythagorean school of thought. His surviving On Mathematics Useful for the Understanding of Plato is an introductory survey of Greek mathematics. Little is known about the life of Theon of Smyrna. A bust created at his death, and dedicated by his son, was discovered at Smyrna, and art historians date it to around 135 CE.
MoraliaThe Moralia (Ἠθικά Ethika; loosely translated as "Morals" or "Matters relating to customs and mores") is a group of manuscripts written in Ancient Greek, dating from the 10th–13th centuries, and traditionally ascribed to the 1st-century scholar Plutarch of Chaeronea. The eclectic collection contains 78 essays and transcribed speeches. They provide insights into Roman and Greek life, but they also include timeless observations. Many generations of Europeans have read or imitated them, including Michel de Montaigne, Renaissance Humanists and Enlightenment philosophers.
John DeeJohn Dee (13 July 1527 – 1608 or 1609) was an English mathematician, astronomer, astrologer, teacher, occultist, and alchemist. He was the court astronomer for, and advisor to, Elizabeth I, and spent much of his time on alchemy, divination, and Hermetic philosophy. As an antiquarian, he had one of the largest libraries in England at the time. As a political advisor, he advocated the foundation of English colonies in the New World to form a "British Empire", a term he is credited with coining.

His father was a minor sophist of the same name. He was born probably around 170, and is said by the Suda to have been living in the reign of emperor Philip the Arab (244–249). His death possibly occurred in Tyre c. 250 AD. Some ambiguity surrounds his name. The name Flavius is given in The Lives of the Sophists and Tzetzes.
