lucius scribonius libo (tribune of the "plebs" 149 bc) was a member of a roman senatorial family. he accused servius sulpicius galba for the outrages against the lusitanians. he might have been the scribonius who consecrated the puteal scribonianum often mentioned by ancient writers, which was located in the forum close to the arcus fabianus. it was called puteal as it was opened at the top, like a well. years later it would be repaired and dedicated by another libo, praetor of 80 bc.
