Clarke's first book, Between Geography and history (1999) discussed how the presentation of geography in Polybius, Posidonius, and Strabo responded to the rise of Roman power. In the book, she argues that geography and geographic ideas were more important and complex in ancient historiography than hitherto realised. W. J. Tatum and R. Alston characterised it as "essential reading" for work on Posidonius, Strabo, and Hellenistic geography.[6][7][8]
Clarke's second book, Making Time for the Past (2008) explores how ancient Greek city-states conceived of time and the past, as a central part of their communal identities. The book was a groundbreaking work for the study of local history in ancient Greece.[9][10]
A third book, Shaping the Geography of Empire (2018) deals with the representation of geography and the physical world in Herodotus' Histories.
