The church itself is a not very large basilica of the purest and simplest type. There is no dome, no approach to Byzantine arrangement, not even the _chalkidikê_ or transept. Two arcades supported by the smaller columns of the former building, showing Ionic capitals of two types, led to an apse of which the arch of triumph has unluckily together vanished. But of the well-wrought _cancelli_, carrying the mind across the sea to St. Clement’s, a large part still remains. The apse has its windows divided by what at first sight seem to be coupled columns--the type which ranges from St. Constantia to the Moissac cloister--but which really form a single block within and without. The walls are of brick; several of the windows are preserved, and in their jambs we see long stones set upright, just as in the primitive work both of England and Ireland. Everywhere we find these witnesses to the universality of the earliest form of Christian architecture. The pavement contains many inscribed stones of various dates. Some are Pagan, recording votes of the city of Elis in the days of the early Emperors; some are Christian, as that which records the zeal of a certain pious reader ἀναγνωστής towards the making of the pavement itself. To the west of the nave is a range of Ionic columns forming the portico, but their arches or entablature has perished. But to the south-west is an attached building where alone the arches are preserved. They are set on the Ionic columns with an intervening stilt set crosswise in a most ingenious fashion. The column becomes a mid-wall shaft.
