This dissertation proposes an ad fontes research on natural theology in Greek Antiquity through Patristics. For this purpose, this work has selected some Greek and Latin sources in order to find the gods of the poets, the gods of the philosophers, the phýsis in biblical tradition and the theologia tripertita. At first, the gods of the poets and philosophers were surveyed in the first two chapters. In these chapters, two approaches to natural theology in Greek philosophy were presented. The first approach dealt with natural theology as a theology of nature. The second approach dealt with natural theology as a rational theology. Then, the phýsis in the biblical tradition of the Old Testament, the Septuagint, and the New Testament was examined. At last, the theologia tripertita (mythical theology, natural theology, and civil theology) was presented in four non-Christian thinkers (Varro, Plutarch of Chaeronea, Dio Chrysostom and Aetius) and five Christians (Tertullian of Carthage, Arnobius of Sica, Lactantius, Eusebius of Caesarea, and Augustine of Hippo).
