by Luther and Calvin became as sacred to their followers as the Scripture itself. For instance, when Georg Calixtus ventured, in interpreting the Psalms, to question the accepted belief that "the waters above the heavens" were contained in a vast receptacle upheld by a solid vault, he was bitterly denounced as heretical. Today, much of the scholarship in which the conflict thesis was originally based is considered to be inaccurate. For instance, the claim that early Christians rejected scientific findings by the Greco-Romans is false, since the "handmaiden" view of secular studies was seen to shed light on theology. This view was widely adapted throughout the early medieval period and afterwards by theologians (such as Augustine) and ultimately resulted in fostering interest in knowledge about nature through time. Also, the claim that people of the Middle Ages widely believed that the Earth was flat was first propagated in the same period that originated the conflict thesis and is still very common in popular culture. Modern scholars regard this claim as mistaken, as the contemporary historians of science David C. Lindberg and Ronald L. Numbers write: "there was scarcely a Christian scholar of the Middle Ages who did not acknowledge [earth's] sphericity and even know its approximate circumference." From the fall of Rome to the time of Columbus, all major scholars and many vernacular writers interested in the physical shape of the earth held a spherical view with the exception of Lactantius and Cosmas. H. Floris Cohen argued for a biblical Protestant, but not excluding Catholicism, influence on the early development of modern science. He presented Dutch historian R. Hooykaas' argument that a biblical world-view holds all the necessary antidotes for the hubris of Greek rationalism: a respect for manual labour, leading to more experimentation and empiricism, and a supreme God that left nature open to emulation and manipulation. It supports the idea early modern science rose due to a combination of Greek and biblical thought. Oxford historian Peter Harrison is another who has argued that a biblical worldview was significant for the development of modern science. Harrison contends that Protestant approaches to the book of scripture had significant, if largely unintended, consequences for the interpretation of the book of nature. Harrison has also suggested that literal readings of the Genesis narratives of the Creation and Fall motivated and legitimated scientific activity in seventeenth-century England. For many of its seventeenth-century practitioners,
