apparently a shrine, known only from a dedicatory
inscription made of white stones in a pavement of opus signinum that
was found in 1854 under the cloister of S. Giovanni Calibita in the northern
part of the island in the Tiber (CIL i. 990
=vi. 379; C. Volcaci(us) C. f.
har(uspex) de stipe Iovi iurario... onimentom
; cf. v. Suppl. ital. 1272;
ILS 3037). Iuppiter iurarius seems to be a translation ofΖεῦς πίστιος
, but whether this was an independent shrine or to be identified
with that of some other deity, e.g. SEMO SANCUS (q.v.), is uncertain
(HJ 636; Rosch. ii. 678
; iv. 319
; WR 131 ; Besnier, 255-271).
