The main room of the ordinary temple was rectangular, with an elevated apsidal arrangement, like a choir, containing the sacred relief on its wall, at the end opposite the entrance, and with continuous benches (podia) of masonry, about 5 ft.
There were arrangements for the brilliant illumination of the choir and its relief, which was sometimes sculptured on both sides and reversible, while the podia were intentionally more obscure.
The choir and the long space between the podia were for ministrants, the podia themselves for kneeling worshippers.
According to this, the shoot of the vine is a "sympodium," consisting of a number of "podia" placed one over the other in longitudinal series.
The absence of an apical system of plates; the fact that radial symmetry has not affected the generative organs, as it has in all other recent classes; the welldeveloped muscles of the body-wall, supposed to be directly inherited from some worm-like ancestor; the presence on the inner walls of the body in the family Synaptidae of ciliated funnels, which have been rashly compared to the excretory organs (nephridia) of many worms; the outgrowth from the rectum in other genera of caeca (Cuvierian organs and respiratory trees), which recall the anal glands of the Gephyrean worms; the absence of podia (tube-feet) in many genera, and even of the radial water-vessels in Synaptidae; the absence of that peculiar structure known in other echinoderms by the names "axial organ," "ovoid gland," &c; the simpler form of the larva - all these features have, for good reason or bad, been regarded as primitive.
