Paciacus, L. Ju'nius
served under Caesar in the Spanish war, B. C. 45. and was sent by Caesar with six cohorts and sotae cavalry to strengthen Ulia. which was besieged by Cn. Pompey. (Auct. B. Hisp.
3; Cic. Fam. 6.18
, ad Att.
12.2.) Paciacus, which Drumnann preserves (Gesch. Roms, vol. iv, p. 52
), is hardly a Roman name. Orelli reads Paciaecus,
which is preferabe ; but it may perhaps be Pacianus,
a name which occurs elsewhere sometimes with one c and sometimes with two. [PACCIANUS, PACIAXUS.]
