Following the road which his innkeeper pointed out, the traveller became so absorbed in the busy movement of the communal threshing-ground, the arrival of the yellow grain, the women who were wielding pitchforks, and the horses moving in circles, with solemn rhythm, that he nearly passed a low building, the object of his search. Nothing could be more quaintly old and modest than the baptistery of Riez. It is a small square building of rough cemented stone whose stucco has worn away. The roof is tiled, and from out a flattened dome, blades of grass sprout sparsely. A tiny bell-turret and an arch in the front wall complete the ornamentation of this humble, diminutive bit of architecture, and except that it is different from the usual Provencal manner of construction, one would pass many times without noticing it. [Illustration: "BETWEEN THE COLUMNS AN ALTAR HAS BEEN PLACED."--BAPTISTERY, RIEZ.] Walking down the steps which mark the differences that time has made in the levels of the ground and entering a small octagonal hall, one of the most interesting interiors of Provence meets the eye. "Each of its four sides," writes Jules de Lauriere, "which correspond to the angles of the outer square, has a semicircular apse built in the walls themselves. The eight columns, placed in a circle about the centre of the edifice, divide it into a circular nave and a central rotunda, and support eight arches which, in turn, support an octagonal drum, and above this is the dome." This room is of simple and charming architectural conception, and even in melancholy ruin, it has much beauty. It gains in comparison with the re-constructed baptisteries of Provence, for something of a primitive character has been preserved to which such modern altars and XVII century trappings as those of Aix and Frejus are fatal. Under the heavy dust there is visible an unhappy coating of whitewash, traces of a fire still blacken the walls, fragments of Roman sculpture are scattered about, and between the columns a pagan altar has been placed for safe-keeping. The columns themselves are of pagan construction, and as they differ somewhat in size and capitals, it is not improbable that they came from the ruins of several of the great public buildings of Riez. At the time of the baptistery's construction, the barbaric invasion had begun, and these Roman monuments may have been in ruins; but in any case, it was a pious and justifiable custom of Christians to take from pagan structures, standing or fallen, stones and pillars that would serve for building churches to the "one, true God." The pillars procured for this laudable purpose at Riez, with their beautiful, carved capitals, gave the little baptistery its one decoration, and far from disturbing the simplicity of its style, they add a slenderness and height and harmony to a room which, without them, would be too stiffly bare. In the rotunda which they form, excavations have brought to light
