This is the way the Greeks made that Line which represents to "the capable eye" the true Attic civilization. And when we examine the innumerable lines of Grecian architecture, we find that they never for an instant lost sight of this Ideal. The fine humanity of it was everywhere present, and mingled not only with such grand and heroic lines as those of the sloping pediments and long-drawn entablatures of the Parthenon and Theseion, bending them into curves so subtilely modulated that our coarse perceptions did not perceive the variations from the dead straight lines till the careful admeasurements of Penrose and Cockerel and their _confrères_ of France assured us of the fact,--not only did it make these enormous harp-strings vibrate with deep human soul-music, but there is not an abstract line in moulding, column, or vase, belonging to old Greece or the islands of the Aegean or Ionia or the colonies of Italy, which does not have the same intensity of meaning, the same statuesque Life of thought. Besides, I very much doubt if the same line, in all its parts and proportions, is ever repeated twice,--certainly not with any emphasis; and this is following out the great law of our existence, which varies the emotion infinitely with the occasion which produced it. Let us suppose, for example, that a moulding was needed to crown a column with fitting glory and grace. Now the capital of a column may fairly be called the throne of Ideal expression; it is the _cour d'honneur_ of Art. The architect in this emergency did not set himself at "the antique," and seek for authorities, and reproduce and copy; for he desired not only an abstract line of Beauty there, but a line which in every respect should answer all the requirements of its peculiar position, a line which should have its individual and essential relationships with the other lines around it, those of shaft, architrave, frieze, and cornice, should swell its fitting melody into the great _fugue_. And so, between the summit of the long shaft and that square block, the abacus, on which reposes the dead weight of the lintel of Greece, the Doric _echinus_ was fashioned, crowning the serene Atlas-labor of the column with exquisite glory, and uniting the upright and horizontal masses of the order with a marriage ring, whose beauty is its perfect fitness. The profile of this moulding may be rudely likened to the upper and middle parts of the line assumed as the representative of the Greek Ideal. But it varied ever with the exigency of circumstances. Over the short and solid shafts of Paestum, it became flat and almost horizontal; they needed there an expression of emphatic and sudden grace; they meet the _abacus_ with a moulding of passionate energy, in which the soft undulations of Beauty are nearly lost in a masculine earnestness of purpose. On the other hand, the more slender and feminine columns of the Parthenon glide into the _echinus_ with gentleness and sweetness, crown themselves with a diadem of
