Galla, Sosia
the wife of C. Silius [SILIUS], involved with him in a charge of treason A. D. 24. The pretext for Galla's impeachment was, that during her husband's command in Upper Germany, in A. D. 14, she had sold her influence with him, and shared in his exactions on the provincials. But the real motive was Galla's intimacy with Agrippina, the widow of Germanicus. Galla was sent into banishment. (Tac. Ann. 4.19, 20.)
