A new fragment of the "Laws about rented oxen" and the Sumerian verb bu-us2

The so-called “Laws about Rented Oxen”, which deal with issues of liability involving injury to or loss of the oxen, were formalized by the instructors of the Old Babylonian edubba and copied repeatedly by the students. Their first reconstruction was published in 1965 by M. Civil, based upon three student exercise tablets from Nippur; later M. Roth arranged the provisions into a single sequence, adding another three fragments containing ox laws. New evidence of three oxen provisions in an unpublished fragmentary prism provides the opportunity to update and call attention to this law collection again. One provision in particular presents the Sumerian verb bu-us2 previously attested only once in a school letter.
