What is "compascuus"

Compascuus is Latin for commonly grazed, and hence often used in the forms ager compascuus (common pasture land) and compascuum (the common pasture). In the early republic, there were three kinds of land, private, public and common pasture. The Lex Agraria, that formalized the existing situation after the land reforms, set limits on how much cattle an individual could graze on ager compascuus without having to pay dues.
