Temple of Portunus. The Temple of Portunus or Temple of Fortuna Virilis is a Roman temple in Rome, Italy, one of the best preserved of all Roman temples.
   Its dedication remains unclear, as ancient sources mention several temples in this area of Rome, without saying enough to make it clear which this is. It was called the Temple of Fortuna Virilis from the Renaissance, and remains better known by this name. If dedicated to Portunus, the god of keys, doors and livestock, and so granaries, it is the main temple dedicated to the god in the city.
   It is in the Ionic order and located by the ancient Forum Boarium by the Tiber, during Antiquity the site overlooked the Port Tiberinus at a sharp bend in the river; from here, Portunus watched over cattle barges as they entered the city from Ostia. The temple was originally built in the 3rd or 4th century BCE but was rebuilt between 120-80 BCE, the rectangular building consists of a tetrastyle portico and cella, raised on a high podium reached by a flight of steps, which it retains.
   Like the Maison Carree in Nimes, it has a pronaos portico of four Ionic columns across and two columns deep. The columns of the portico are free-standing, while the remaining five columns on the long sides and the four columns at the rear are half-columns engaged along the walls of the cella.
   This form is sometimes called pseudoperipteral, as distinct from a true peripteral temple
