“I will erect such a building, but I will hang it up in the air,” exclaimed Michael Angelo when he saw the dome of the Pantheon at Rome. The reader may remember this boast of the great Renaissance genius, the fulfilment of it in the colossal dome of St. Peter’s, and be satisfied that his memory has captured one architect of celebrity. If the beautiful Florentine campanile of Giotto looms up in his recollection he will think at once also of that early artist, but perhaps not more so in connection with that ornate tower than in association with the Pre-Raphaelites. Of course, he will not overlook Inigo Jones, whose very name is stamped upon the memory by reason of its peculiarity, or Sir Christopher Wren, the creator of St. Paul’s, and the British idol. If he is an admirer of the picturesque architecture of Venetian churches and palaces, the Italian Palladio may not escape him; and if of French Renaissance, the Louvre façade will possibly suggest Perrault, and the Parisian roofs Mansard. If he is a native of our “Modern Athens,” of course, the peril in which the classic front of the State House rested for a time, at the hands of a _fin de siècle_ legislature, will not permit him to forget Bulfinch, and Trinity Church will bring to memory the only Richardson. But aside from a few names such as have been mentioned, with possibly a sprinkling of others fixed in the memory, by incident or association, the average reader, however well acquainted he may be with the numerous luminaries of the other arts, will be unable to say who was responsible for the beauty and nobility of many buildings that have individualized the cities and towns of their location to the art-loving world. Who, for example, can tell of the authors of the cathedrals at Milan and Siena, Cologne and Strassburg, Rheims and Amiens, Wells and Litchfield; the Giralda at Seville; the Church of the Invalides at Paris; the Strozzi Palace at Florence; the Henry VII. chapel at Westminster Abbey; the much and justly admired south façade of the old City Hall in New York; Grace Church in that city; the Capitol building in Washington, or that model of colonial architecture in America, the Executive Mansion? It is not, however, the purpose to here speculate too extensively upon the apparent lack of justice on the part of the general public which has been done the architects of all climes and times, but to gather together a few facts concerning the Old Masters of early Grecian architecture that are not popularly known, and recall some of the leading lights of that art so inimitably practised by the Hellenic people during their progress from archaic darkness to the zenith of their æsthetic culture.
