From the earliest stages of Greek thought, sound was thought to originate as the result of an impact between two objects. At first it was believed that the swiftness and force of the impact affected both volume and pitch; then it became clear that these were two different parameters. Pitch, in particular, was connected either to quantitative factors, such as the speed of the movement or the number of subsequent impacts, or to qualitative ones, like the idiotes (“peculiarity”) theorized by Theophrastus. The least investigated parameter of sound is timbre, which was usually attributed to the physical characteristics of the source.

Agathinus (Claudius Agathinus) a Spartandoctor of the 1st cent. CE, associated with the medical sect of the *Pneumatists and by at least one ancient source with the establishment of an eclectic medical sect founded on Pneumatism with additional doctrines from medical Empiricism and *Methodism. He was a pupil of *Athenaeus (3) of Attaleia, and was linked with the Stoic philosopher L. *Annaeus Cornutus. He may have taught the physicians *Archigenes and *Herodotus (2). Fragments of his doctrines are reported by *Galen and *Oribasius, amongst others. He wrote influential works on pulsation (grudgingly praised by Galen, 8. 748 Kühn), on semi-tertian fevers, and on the use of hellebore; little is now known of their contents.
Appears in *Hyginus (3) (Fab.274) in a list of discoverers and inventors. She is described as an Athenian girl who lived at a time when there were no *midwives, because women and slaves were forbidden to learn medicine; this scenario matches no known historical period. Disguising herself as a man, Agnodice studied medicine under ‘a certain Herophilus’, and then practised medicine at Athens successfully, challenging the professional monopoly on the part of male doctors. Accused by her jealous rivals of seducing her patients, Agnodice demonstrated her innocence by performing the gesture of anasyrmos, lifting her tunic to expose her lower body. This revelation led to a charge of practising medicine unlawfully, but she was saved when the wives of the leading men lobbied the *Areopagus in her defence. Hyginus claims that Athenian law was then changed so that freeborn women could study medicine.
