Levau, the latter's architect, made the necessary alterations to the structure already existing, and little by little the more magnificent project known in its completed form to-day was evolved. War not being actually in progress, or imminent, great bodies of soldiery were set at work with pick and shovel, and at one time thirty thousand had laid aside their sabres and muskets for the more peaceful art of garden-making under the direction of Le Notre. In three decades the sum total of the chief roll of expenses of the palace and its dependencies reached eighty-one million, one hundred and fifty-one thousand, four hundred and fourteen _livres_, nine _sols_ and two _deniers_. It is perhaps even more interesting to know that of this vast sum more than three millions went for marble, twenty-one millions for masonry, two and a half millions for the rougher woodwork and a like sum for marquetry. Other additional "trifling" embellishments of Versailles and the Trianon during the same period counted up another six million and a half. The expense of these works was enormous on all sides. Water being required for the purpose of supplying the fountains it was proposed that the waters of the Eure should be turned from their original bed and made to pass through Versailles, and the enterprise was actually begun. Beyond the gardens was formed the Little Park, about four leagues around, and beyond this lay the Great Park, measuring twenty leagues around and enclosing several forest villages. The total expenses of these works may never have been exactly known, but they must have been immense, that is certain, and have even been estimated at as much as one billion francs. The works were so far completed in 1664 that the first Versailles fete was given to consecrate the palace. In honour of this event Moliere composed "La Princesse d'Elide." The improvements, however, were continued, and in 1670, Levau, dying, was succeeded by his nephew, Jules Hardouin Mansart, who wished to destroy the chateau of Louis XIII and erect one uniform building. Louis XIV, out of respect to his father, would not allow Mansart's project to be carried out and therefore alterations were only made in the court by surrounding it on the western side with the magnificent buildings now forming the garden front. The southern wing was subsequently added for the accommodation of the younger members of the royal family. In 1685 the northern wing was erected to meet the requirements of the attaches of the court. The chapel was commenced in 1699 and finished in 1710.
