## Aristaeus

(716 words)

*Aristaîos*). [German version] [1] Greek rural deity Rural deity linked with sheep, the discovery of olive oil and honey, hunting, healing, prophecy and the end- ing of a period of drought on Ceos (cf. Apoll. Rhod. 2,500 ff.). In literature he is famous for the death of his bees, which occurred because he was responsible for the death of Euridices, and he successfully searched for ways to restore the bee populations (Verg. G. 4,315-558). A. is a complex figure who can be found in Central Greece, in Arcadia, on Ceos and in Cyrene. He was the husband of Auto…

## Quadrature of the circle

*ho toû kýklou tetragōnismós*, Latin

*quadratura circuli*). [German version] I. The nature of the problem The quadrature of the circle is one of the three 'classic problems' (the other two being the trisection of an angle, cf. division of angles and circles, and the duplication of the cube) of ancient Greek mathematics. The problem is to find the side

*x*of a square such that its area is equal to the area of a circle with radius

*r*using a geometric procedure; that is, to determine the value of the variable

*x*in the equation

*x*2 = π

*r*2. Accordingly, the solution to the q…

## Theudius

(210 words)

*Theúdios*). Mathematician and philosopher from Magnesia, probably 4th century BC. The only information about him comes from the catalogue of mathematicians in Proclus's [2] commentary on Euclid [1. 67, Z. 12-20]. T. is mentioned there after Eudoxus [1] and before Philippus of Medma, who was a pupil of Plato [1]; Therefore, T. was probably a contemporary of Aristotle [6]. According to Proclus, T., Menaechmus [3] and Deinostratus conducted research together at the Academy (

*Akadḗmeia*), improved the arrangement of the

*'Elements'*, and put many limited pr…

## Eutocius

(168 words)

*Eutókios*) The mathematician E. of Ascalon was presumably born around AD 480; the widespread assumption that he was a pupil of the architect Isidorus of Miletus is hardly plausible [1. 488]. He wrote commentaries on three works of Archimedes [1] (

## Mechanical method

(255 words)

*Éphodos*) of Archimedes [1] is our source for his mechanical method from which he derived geometric formulas. To compare the surfaces of two figures, he disassembled each into an infinite number of parallel lines and balanced them on a scale. On one side of the scale, one surface is hung up at one point, i.e., as a whole. On the other side, the surface is hung up along the entire arm, i.e., each layer remains where it is and acts with a different leverage. When ea…

## Diocles

(2,746 words)

*Dioklês*). [German version] [1] Hero in Megara Hero in Megara. He supposedly died in battle, bravely covering a youth with his shield. At his grave boys competed for who could give the sweetest kiss. This agon, which took place every spring, was called Dioclea (Schol. Pind. Ol. 7,157; 13,156a; Theoc. 12,27-33 with Schol.: Aition). Perhaps the kisses represented farewell kisses repeated in the cult of the hero ([1]; to the contrary [2]). According to Schol. Aristoph. Ach.774 the agon was founded…

[German version] [1] of Cnidus Ancient mathematician and astronomer One of the most important ancient mathematicians and astronomers, he was presumably born in 391/390 BC (on the problem of dating see [7. 137-139]). He studied mathematics with Archytas [1] and medicine with Philistion. At the age of 23 he went to Athens and it is said that, among other things, he attended lectures there with Plato. At the expense of his Cnidian friends, presumably in 365/4 [11], E. went with a letter…

*Akadḗmeia*). In Plato's [1] dialogue named after him, T. appears (together with the aged Theodorus [2]) as about fifteen years old in 399 BC; he was therefore born
