The emergence of a systematic literature around land-surveying in the late first century AD affords an ideal opportunity to study the development of an ars within the scientific culture of specialized knowledge in the early Roman Empire. The variegated methods that belonged to the historical inheritance of surveying practice challenged the construction of a discrete and coherent disciplinary identity. The surveying writings of Frontinus and Hyginus evince several strategies intended to produce a systematic and explanatory conception of the ars. These include rationalizing explanations of key surveying terminology and practice with a view to natural first principles and an accounting of surveying methods in interdisciplinary perspective with astronomy, natural philosophy, and mathematics. While these earliest surveying works pose several unique challenges, they ultimately provide a precious window onto the challenges and opportunities that greeted the emergence of an ars in the fervid scientific culture of the period.
