This set forth to all generations the form which the new temples were thenceforth to take after His death on the Cross.
"This sufficiently accounts for the cruciform plan of our churches.

But we will study the inside of the church later; for the present we must consider the meanings of the external parts of a cathedral.
"The towers and belfries, according to the theory of Durand, Archbishop of Mende in the thirteenth century, are to be regarded as preachers and prelates, and the lofty spire is symbolical of the perfection to which their souls strive to rise.

According to other interpreters of the same period, such as Saint Melito, Bishop of Sardis, and Cardinal Pietro of Capua, the towers represent the Virgin Mary, or the Church watching over the salvation of the Flock.
"It is a certain fact," the Abbe went on, "that the position of the towers was never rigidly laid down once for all in mediaeval times; thus different interpretations are admissible according to their position in the structure.

Still, perhaps the most ingeniously refined, the most exquisite idea is that which occurred to the architects of Saint Maclou at Rouen, of Notre Dame at Dijon, and of the Cathedral at Laon, for example, who built rising from the centre of the transepts--that is above the very spot where, on the Cross, the breast of Christ would lie, a lantern higher than the rest of the roof, often finishing outside in a tall and slender spire, starting as it were from the Heart of Christ to leap with one spring to the Father, to soar as if shot up from the bow of the vaulting in a sharp dart to reach the sky.
"The towers, like the buildings they overshadow, are almost always placed on a height that commands the town, and they shed around them like seed into the soil of the soul, the swarming notes of their bells, reminding all Christians by this aerial proclamation, this bead-telling of sound, of the prayers they are commanded to use and the duties they must fulfil; nay, at need, they may atone before God for man's apathy by testifying that at least they have not forgotten Him, beseeching Him with uplifted arms and brazen tongues, taking the place as best they may of so many human prayers, more vocal perhaps than they." "With its ship-like character," said Durtal, who had thoughtfully approached the window, "this Cathedral strikes me as amazingly like a motionless vessel with spires for masts and the clouds for sails, spread or furled by the wind as the weather changes; it remains the eternal image of Peter's boat which Jesus guided through the storm." "And likewise of Noah's Ark--the Ark outside which there is no safety," added the Abbe.
"Now consider the church in all its parts.

Its roof is the symbol of Charity, which covereth a multitude of sins; its slates or tiles are the soldiers and knights who defend the sanctuary against the heathen, represented by the storm, its stones, all joined, are, according to Saint Nilus, emblematic of the union of souls, or, as the _Rationale_ of Durand of Mende has it, of the multitude of the faithful; the stronger stones figuring the souls that are most advanced in the way of perfection and hinder the weaker brethren, represented by the smaller stones, from slipping and falling.
