Horos of Hymettian stone found in Kerameikos by the German Archaeological Institute under Bau Z3. On "contributors" (eranistai) as ongoing associations rather than merely ad hoc loaning groups, see the recent study by Thomsen 2015. The phrase "sold on condition of release" (πεπραμένων ἐπὶ λυσει) denotes not an actual sale, but the offering of securities for a loan with an expectation that the pledged securities would be "released" upon repayment of the loan.
