Pompeii, Its Life and Art. August 1840-1909 Mau
was found: V[ibius] Popidius Ep[idii] f[ilius] q[uaestor] porticus faciendas coeravit, 'Vibius Popidius, the son of Epidius, when quaestor caused this colonnade to be erected.' No clew to the date is given, but it must have been before the coming of the Roman colony, for after that time there was no office of quaestor in Pompeii. It must also have been before the Social War; in those years of tumult an extensive colonnade would not have been built, and when the national spirit was so vehemently asserting itself, we should expect to find inscriptions upon public works in the Oscan language, certainly not in Latin. But the use of Latin may very well date from the latter part of the period of alliance with Rome; we may then with much probability assign the inscription to the second half of the second century B.C.
Remains of the colonnade of Popidius are still to be seen on the south side, and on the adjoining part of the east side, extending just across Abbondanza Street; traces of it are found also on the west side, where it was afterward replaced by a new structure. On the east side north of Abbondanza Street no traces remain; the appearance of this part of the Forum was entirely changed when the four buildings (K, L, M, N) with their porticos were erected, but we can hardly doubt that the original colonnade extended here also. Our illustration (Fig. 14) shows the arrangement of the Doric columns in the lower story; of the Ionic columns above only scanty fragments have been recovered. The appearance of the whole may be suggested by our restoration (Fig. 13).
In style and construction this colonnade belongs to the Tufa Period (p. 40). While the forms are not those of the classical period, they nevertheless manifest Greek feeling. The low ratio in the proportions of the Doric columns, of which the height is equal to five diameters, well accords with their use as a support for an upper gallery; elsewhere in pre-Roman Pompeii more slender proportions are preferred, even for the Doric style. The shaft is well shaped, with a moderate swelling (entasis). Only the upper part is fluted; as the sharp edges of the flutings near the bottom might easily be marred, the divisions of the surface on the lower third of the shaft were left flat.
The architrave is relatively low, the result of an interesting peculiarity in the method of construction. Blocks of tufa long enough to span the intercolumniations were too weak to sustain the weight of the rest of the entablature. To meet this difficulty a line of thick planks was placed in old Italic fashion above the capitals of the columns, and on these were laid short tufa blocks. Thus in our illustration (Fig. 14), while the upper of the two bands of the architrave is seen to be of stone, the lower shows the modern timber supplied in the place of the ancient. That the planks were in reality no thicker than has been assumed in the reconstruction is proved beyond question by the later colonnade on the west side, which, although entirely of stone, corresponds throughout in its proportions with the older one; the architrave is equally narrow, and is likewise divided into two parts.

This explanation is curiously confirmed by an architectural painting on the garden wall of one of the finest houses of the Tufa Period, the house of the Faun. Here we find pilasters and entablature, except the architrave, painted white; but the architrave is painted in two bands, of which the lower is yellow, as if to represent wood. Nothing would have been easier than to leave the architrave, moulded in stucco, of one color as if it were all of one material; but special effort was made apparently to indicate the appearance of a lower division of timber. From this we may infer that in actual construction no pains was taken to conceal the lack of uniformity in structural materials by laying a coat of white or colored stucco over wood and stone alike; on the contrary, the difference was not only recognized in the decoration, but even accentuated, as the timber, whether retaining its original color or painted with a suitable tint, presented a marked contrast with the stone the surface of which was covered with white stucco. If the strip of timber in the architrave had been perceptibly thicker than that of stone above it, the effect would not have been good; as the earlier Greek polychrome decoration was now no longer in vogue, the stripe of color above the capitals made a pleasing variation from the prevailing whiteness of the structure.
The Basilica at the southwest corner and the temple of Jupiter both conform to the same variation from the direction of the early north and south street that we have noticed in the case of the colonnade of Popidius; they belong, therefore, to the same remodelling of the Forum. It is quite possible that the erection of the temple, by limiting the area of the Forum on the north side, caused its extension toward the south beyond the earlier boundary. Originally the temple was isolated, the north end of the Forum on either side being left open; later, but still in the time of the Republic, a high boundary wall with passageways was built on both sides of it. Later still the two arches were erected in a line with its façade; afterwards, in the time of Tiberius, the wall at the right of the temple was replaced by the commemorative arch (I), and the smaller arch near the façade at the right was removed in order that there might be an unimpeded view of the great arch from the area.
The colonnade of Popidius may have stood for more than a century; the necessity of making thoroughgoing repairs no doubt became urgent. In the meantime, however, the taste of the Pompeians had undergone a change, and instead of repairing the old colonnade they began to replace it by a new one, a part of which is shown in Fig. 15. Better material, the whitish limestone, was used, and the construction was more substantial; the blocks of the entablature were fitted together so as to form a flat arch. Though the new colonnade followed closely the proportions of the old, effective details, such as the fluting of the columns, and the triglyphs with the guttae underneath, were omitted. The refined sense of form characteristic of the earlier time was no longer manifest; all is coarse and inartistic, the swelling on the shafts of the columns, for example, being carried too high.

The new colonnade had a second story of the Ionic order, of the columns of which (though not of the entablature) considerable fragments have been found. The stylobate on which the columns rested was renewed in limestone, and about the same time the Forum was paved and the ledge over the gutter was laid with flags of the same material.
This second remodelling of the Forum commenced in the early years of the Empire, the pavement having been laid before the pedestal of the monument to Augustus was built. It was never carried to completion. On the west side the new colonnade was almost finished when the earthquake of the year 63 threw it nearly all down. At the time of the eruption only the columns at the south end of this side, which had safely passed through the earthquake, were still standing with their entablature; they are shown in Fig. 15. The area was then strewn with blocks, which the stonecutters were engaged in making ready for the rebuilding.
The Forum of Pompeii, as of other ancient cities, was first of all a market place. Early in the morning the country folk gathered here with the products of the farm; here all day long tradespeople of every sort exhibited their wares. In later times the pressure of business led to the erection of separate buildings around the Forum to relieve the congestion; such were the Macellum, used as a provision market; the Eumachia building, erected to accommodate the clothing trade; the Basilica and the market house west of the temple of Jupiter, devoted to other branches of trade. Yet in a literal sense the Forum always remained the business centre of the city.
It served, too, as the favorite promenade and lounging place, where men met to discuss matters of mutual interest, or to indulge in gossip. Here idlers loitered and plied busier men with questions regarding public affairs, makers and dealers came together to talk over and settle points of difference, and young people pursued their romantic
