8The HYPÆTHROS is decastylos, in the pronaos and posticum. In other respects it is similar to the dipteros, except that in the inside it has two stories of columns all round, at some distance from the walls, after the manner of the peristylia of porticos. The middle of the interior part of the temple is open to the sky, and it is entered by two doors, one in front and the other in the rear. Of this sort there is no example at Rome, there is, however, an octastyle specimen of it at Athens, the temple of Jupiter Olympius.
8The hypaethral is decastyle in both front and rear porticoes. In everything else it is the same as the dipteral, but inside it has two tiers of columns set out from the wall all round, like the colonnade of a peristyle. The central part is open to the sky, without a roof. Folding doors lead to it at each end, in the porticoes in front and in the rear. There is no example of this sort in Rome, but in Athens there is the octastyle in the precinct of the Olympian.
