[22] Tholos: A circular building; used in archæological writing to describe one whose purpose is not certainly known, as the Tholos of Atreus at Mykenai, generally thought to be a tomb; that near Epidauros thought by some to be the spring-house, or the sacred well of Asklepios.
[23] Choragic: Having to do with the Choragos, the manager of the sacred chorus in Athens. This was an honorary post involving much expense and labor to the occupant.
[24] Hypæthral: Open to the sky; Hypæthral opening, a space uncovered, part of a Greek temple, perhaps entirely unroofed, perhaps only having a roof partly opened in sky-lights. Hypæthral Theory: any one of several opinions as to the possible lighting of the interior of a temple from above, either through the roof, or by the partial omission of a roof so as to form a central open court.
[25] Risorgimento: In Italian, a new arising; this is the common term for the revival of classical learning in the fourteenth and fifteenth centuries, coupled with the advance in expressional painting and sculpture of the same epoch, and developing later in the revival of classical design in architecture. The term Rinascimento (rebirth) is used in the same sense, but is apparently rather a reflection of the prevailing French word Renaissance. It would be well if English writers would employ the term Risorgimento for the Italian movement of the fourteenth and fifteenth centuries, and Renaissance for the French movement of the sixteenth century with its equivalents in northern Europe. As for Spain, in which the classical revival followed very closely upon that of Italy, the term Renacimiento seems to correspond very closely to the Italian Risorgimento and the French Renaissance.
[26] Cupola: A cup-shaped roof, either built of solid masonry and so really a vault, or a mere decorative shell.
[27] Groin-vaulting: Vaulting in which one barrel vault meets and intersects another, so that the projecting solid angles, called groins, are formed by the meeting of the hollow rounded surfaces.
[28] Nave: In a building with three or more parallel subdivisions, forming together one great hall, like a large Gothic church, that part which rises highest, and has generally windows above the roofs of the lower aisles.
[29] Aisle: See the definition of nave.
[30] Barrel-vault: A vault whose cross-section is everywhere the same as if part of a tube.
[31] In antis: Latin, between the antæ. The anta is the end of a wall treated so as to be an almost independent member, like a square pillar in which the wall ends. The portico made by two of these set opposite one another and with columns between, is said to have two columns or four columns in antis.
