45 • UPPER HALF I TEMPLE OF MINERVA MEDICA, ROME, f. A,D. 250. LOWER HALF: MICHEL- O22O*S ROTUNDA AT THE EAST END OF THE SS. ANNUNZIATA, FLORENCE, BEGUN 1444. THE FIRST CENTRAL PLANS OF THE RENAISSANCE However, one more central building, or rather part of a building, was begun shortly after S. Maria degli Angeli and completed, and this is a direct copy of an existing Roman monument. Michel- 0220 (1396-1472) began in 1445 to add to the mediaeval church of the SS. Annunziata a round east end with eight chapels or niches exactly as he had seen it done in the so-called temple of Minerva Medica in Rome (fig. 45). So while in the early works of Brunelleschi we cannot too much emphasise the independence of the new forms from those of Roman antiquity, the discovery of how much could be learned from Rome to satisfy topical aesthetic needs came as early as the thirties and forties That it appears most clearly in centrally planned buildings is eminently characteristic. For a central plan is not an other-worldly, but a this-worldly conception. The prime function of the mediaeval church had been to lead the faithful to the altar. In a completely centralised building (fig. 44) no such movement is possible. The building has its full effect only when it is looked at from the one focal point. There the spectator must stand and, by standing there, he becomes himself "the measure of all things". Thus the religious meaning of the church is replaced by a human one. Man is in the church no longer pressing forward to reach a transcendental goal, but enjoying the beauty that surrounds him and the glorious sensation of being the centre of this beauty. No more telling symbol could have been conceived for the new attitude of the humanists and their patrons to Man and religion. Pico della Mirandola, one of the most interesting of the philosophers round Lorenzo the Magnificent, delivered an address in 1486 on The Dignity of Man. M^chiavelli, a little later, wrote his book The Prince to glorify the power of Man's will, and set it as the prime moving force against die powers of religion that had up to his time inter- fered with practical thought. And again a little later Count Castig- lione composed his Courtier to show his contemporaries their ideal of universal man. The courtier, he says, should be agreeable in his 83
