On Seed, the Physis of the Child, Diseases IV by Hippocrates and the Hippocratic Corpus
The title joins three Hippocratic treatises, On Seed, On the Physis of the Child and Diseases IV, which form one continuous work by a single unknown author, written in Ionic Greek in the late fifth or early fourth century BCE; the first is listed under the title On Birth. On Seed argues that seed comes from every part of the body of both the man and the woman, and that what each contributes, and its strength, decides whether the child is a boy or a girl and which parent it resembles. On the Physis of the Child follows the seed in the womb as it draws breath, forms a membrane and is fed by the mother's blood, recalls an embryo of six days that the author says he saw, and sets beside its growth that of a plant from its seed.
Diseases IV opens by recalling how seed comes from all the limbs and sets in the womb, then turns to the four kinds of fluid in the body, phlegm, blood, bile and water, from which, it says, every nousos arises that does not come from violence. Each has its source, the head, the heart, the region by the liver and the spleen, and all are fed from the belly. The author argues that each nousos is decided on odd days, and ends on hydrōps and the signs of each of its forms.

Περὶ Γενέσεως On Birth
On Birth is a concise medical treatise from ancient Greece, composed in Ionic Greek and preserved within the Hippocratic Corpus. Although traditionally attributed to Hippocrates, it is the work of an unknown author, likely dating to the fifth or fourth century BCE. The text comprises eleven sections devoted exclusively to human reproduction, systematically addressing the formation of the embryo from the union of male and female seed, the physiological conditions necessary for conception, the factors believed to determine the sex of the child, and the perceived causes of infertility. The treatise survives intact through medieval manuscript traditions of the Hippocratic collection. It exemplifies the naturalistic and empirical approach characteristic of Classical Greek medicine, seeking material explanations for biological processes rather than attributing them to divine intervention. Scholarly analysis suggests the work was intended for practical use by physicians and medical trainees. Its embryological theories, which belong to the period preceding Aristotle, often employ analogical reasoning, such as comparing fetal development to the growth of a plant. As a component of a broader set of texts concerning women's health, On Birth underscores the significant social and professional attention accorded to childbirth and gynecological knowledge in the ancient world.

Περὶ τῆς Φύσεως τοῦ Παιδίου On the Physis of the Child
On the Nature of the Child is a gynecological and embryological treatise from the Hippocratic Corpus, the collection of ancient Greek medical works associated with Hippocrates and his school. Composed in Ionic Greek during the late fifth or fourth century BCE by an unknown author, it presents a systematic and naturalistic theory of human reproduction. The work details the processes from conception through childbirth, positing that both male and female contribute generative seed, whose mixture and subsequent heating within the womb initiate embryonic formation. It describes fetal development as a process of solidification and differentiation, famously illustrated by an analogy to the curdling of milk, and asserts that the growing embryo is nourished by the mother's blood. Structured as a coherent treatise of approximately twenty sections, the text survives through medieval manuscript tradition. It exemplifies the application of pre-Socratic philosophical inquiry to medicine, seeking physical explanations for biological phenomena and aiming to provide a rational foundation for the practices of gynecology and obstetrics. While its specific physiological models were later refined, the treatise stands as a crucial document for understanding the development of embryological thought in classical antiquity.

Περὶ Νούσων τὸ Τέταρτον Diseases IV
The treatise opens from conception and sets out four fluids in the body, phlegm, blood, bile and water, each with its source: the head, the heart, the region by the liver and the spleen, all fed from the belly. It argues that each nousos is decided on odd days, and that the inflammation of wounds subsides by a fixed count, on the third, fifth, seventh, ninth or eleventh day, and in the largest wounds on the fourteenth. It ends on dropsy, its three forms and the signs of each.
