t., and the right 17 ft. 6
in. The _prothesis_ and _diakonikon_ are square, and a long _schola
cantorum_ forms a continuation to the presbytery westward, though it is
less in width. The westward angles of the aisles also have rectangular
rooms walled off. The whole surface was covered with mosaic, of which a
great deal is still preserved, consisting of geometrical pattern work
for the most part, without inscriptions, though there is one panel
showing a vase with scrolls issuing from it. A large drawing to scale
has been made of it, which is in the communal palace. It took a full
year's labour to complete. The basilica was built between 425 and 443,
but there was a villa there previously, of which considerable remains
were discovered in 1890, at the same time that the first sarcophagi came
to light.

In the modern chapel of S. Caius, pope and martyr, the side of an
antique sarcophagus serves as altar-frontal. It is sculptured with the
deeds of Hercules. The subjects are the Killing of the Dragon of the
Hesperides (which the peasantry mistake for the Garden of Eden),
Alcestis being brought back from Hades, and the Binding of Cerberus. The
water which filtered into the sarcophagus believed to be the tomb of S.
Caius was credited with the same miraculous powers as the "Manna" of S.
Nicola at Bari.

[Illustration: A MORLACCO FAMILY, BETWEEN SALONA AND CLISSA

_To face page 314_]

A path skirts the wall of Salona to the Porta Andetria upon the Clissa
road, which climbs the hillside in well-graded curves. To the north the
ridge of Kozjak rises to the height of 2,000 ft.; across the gap up
which the Roman Via Gabiniana ran, the course of which the modern road
follows, beyond Clissa, the still higher crests of Mosor frown. The
isolated rock on which the fortress stands appears to have been an
outwork of Salona in Roman times, and some assume that it was Andetrium,
which others place farther off; the Byzantines called it Clausura. It is
the key between Sinj and Spalato, its possession effectually closing the
pass to an enemy. The Avars took it in 640 by stratagem, disguising
themselves as Romans. It was Turkish from 1537 till 1669, except for
a short period, and one of the attempts of the Spalatines to possess
themselves of it has been referred to. The fort has three terraces, and
retains a characteristic building, a mosque of Turkish times, now used
as an ammunition store. Round arches which sustain the dome spring from
sta
