Description of rev. is uncertain; the one given here is just a translation of D, but it looks rather different from 2-3. A. Geissen (in litt.) wonders if the 'bull' might just be a 'pedestal? with snake'. Legend too is not certain, as Friedländercommented, but MEN- is clear on 2, and the letters EITHC on 1, so legend given here seems most likely at the moment. The design (if as described) continued under Trajan (D6296), and both MEM- (as on 2776) and MEN- occur later.
