With a similar purpose, a colonnade of the Doric order was built along two sides of the triangular level space about the Greek temple (1). In front of the north end, where the two arms of the colonnade meet, a high portico of the Ionic order was erected (A) facing the street, thus forming a monumental entrance to the Theatre. The southwest side of the area was left unobstructed, and the place, by reason of its shape, is called the Forum Triangulare, 'Three-cornered Forum.' In connection with the building of the Theatre land had been expropriated and cleared as far north as the first east and west street. Here, near the entrance of the Forum Triangulare, a Palaestra for gymnastic exercises (C) was built, with funds left for public purposes by a benevolent citizen. Later, probably not before the time of the Roman colony, a temple of Isis (I) was erected, adjoining the Theatre on the northeast. Early in the Roman Period, not long after 80 B.C., a small roofed theatre (F) was constructed east of the stage of the Large Theatre and of the area at the rear. Stabian Street north and south of the Small Theatre was lined with private houses. At the northeast corner of the block was a temple of Zeus Milichius (H), seemingly of early date, but entirely rebuilt about the time that the Small Theatre was erected. * * * * * Part of the columns and entablature belonging to the beautiful portico at the entrance of the Forum Triangulare have been set up again and are seen in our illustration (Fig. 60). The brackets projecting from the rear wall were probably designed for statuettes or vases. When the wall was rebuilt, after the earthquake of 63, a change was made in at least one particular. The small doorway at the middle, now at right angles with the wall, formerly passed obliquely through it, opening toward the end of the promenade which was laid out in front of the colonnade at the left. This promenade (2 on Plan III) was separated from the area of the Forum by a low wall; on sunny winter days it must have been the most frequented walk in the city. [Illustration: PLATE III.--THE GREEK TEMPLE AND THE FORUM TRIANGULARE, SEEN FROM THE SOUTH. RESTORATION BY WEICHARDT] Besides the small doorway, which was closed by a latticed gate hung from a wooden jamb, there was at the left a massive double door with strong bolts, inside of which was still a second door. It seems odd that one entrance should be so securely closed, while the fastenings of the other were so light. Ordinarily, the large doors must have been kept shut, while the small entrance was left open for everyday use; but when there was to be a play in the Theatre, and the magistrate who gave the entertainment proceeded from the Forum with a retinue in festal attire, then the great doors were swung back in honor of the occasion, and the opening of them formed part of an impressive ceremony.
