went out of the Via Sacra between the Temple of Saturn and the
Basilica Julia, running under the Capitol to the Porta Carmentalis,
the gate in the wall from the Capitol to the river that led into the
forum of the vegetable-dealers. Where it left the Via Sacra it was
spanned by the Arch of Tiberius, erected A.D. 16 in commemoration of
the lost eagles of Varus being recovered by Germanicus (Tacitus,
"Annals," ii. 41). In this street was the Lacus Servilius.
