 The work of Augustine’s most likely to be known to modern students of political thought is The City of God. Although this work was often copied in the middle ages (382 manuscripts have  survived),[10]  a reading of the whole work was never part of the university curriculum. Extracts from it were included in influential anthologies, such as Gratian’s Decretum and Peter Lombard’s Sentences (c.  1150).[11]
