On Semen
''On Semen'' (''De Semine''), also known as ''On the Seed'' (''Peri spermatos'') is a medical treatise written by the Greek physician Galen. In this work, Galen writes about the physiology of animal reproduction, provides detailed anatomical descriptions of the reproductive organs and their purposes, and also deals with inheritance and embryology. The first book of ''On Semen'' is about the contribution of the male to reproduction, and the second book deals with the contribution of the female. Galen wrote it in the 170s, during his second stay in Rome. It was meant for a large audience that did not need much prior medical knowledge to understand it. The focus of ''On Semen'' is, firstly, to criticize Aristotle's concept of semen, and secondly, to propose a new one. Going against Aristotle's view that only males produce a reproductive fluid (semen), but agreeing with Hippocrates, Galen defends a two-seed theory which states there is both a male and a female semen, and that concept ...

Claudii Galeni Opera Omnia
The gens Claudia (), sometimes written Clodia, was one of the most prominent patrician houses at ancient Rome. The gens traced its origin to the earliest days of the Roman Republic. The first of the Claudii to obtain the consulship was Appius Claudius Sabinus Regillensis, in 495 BC, and from that time its members frequently held the highest offices of the state, both under the Republic and in imperial times.''Dictionary of Greek and Roman Biography and Mythology'', vol. I, p. 762 ("Claudia Gens"). Plebeian Claudii are found fairly early in Rome's history. Some may have been descended from members of the family who had passed over to the plebeians, while others were probably the descendants of freedmen of the gens. In the later Republic, one of its patrician members voluntarily converted to plebeian status and adopted the spelling "Clodius". In his life of the emperor Tiberius, who was a scion of the Claudii, the historian Suetonius gives a summary of the gens, and says, "as ...

Peri Alypias
''Peri Alypias'' (), also known as ''De indolentia,'' is a treatise composed by Galen after a massive fire in the centre of Rome in 192AD. Galen's original Greek text was considered lost until it was discovered in 2005 in the library of the Vlatades Monastery, Vlatadon Monastery in Thessaloniki by then-PhD student Antoine Pietrobelli. Prior to its rediscovery, Galen's ''Peri Alypias'' was only known from fragmentary references and quotes in Arabic and Hebrew, and the title was mentioned in Galen's ''On My Own Books (De Libris Propiis)''.
