The dusky labyrinth of the streets, we must in default of such initiations content ourselves with noting, is interrupted by two great candid spaces: the fan-shaped piazza, of which I just now said a word, and the smaller square in which the cathedral erects its walls of many-coloured marble. Of course since paying the great piazza my compliments by moonlight I have strolled through it often at sunnier and shadier hours. The market is held there, and wherever Italians buy and sell, wherever they count and chaffer - as indeed you. hear them do right and left, at almost any moment, as you take your way among them - the pulse of life beats fast. It has been doing so on the spot just named, I suppose, for the last five hundred years, and during that time the cost of eggs and earthen pots has been gradually but inexorably increasing. The buyers nevertheless wrestle over their purchases as lustily as so many fourteenth-century burghers suddenly waking up in horror to current prices. You have but to walk aside, however, into the Palazzo Pubblico really to feel yourself a thrifty old medievalist. The state affairs of the Republic were formerly transacted here, but it now gives shelter to modern law-courts and other prosy business. I was marched through a number of vaulted halls and chambers, which, in the intervals of the administrative sessions held in them, are peopled only by the great mouldering archaic frescoes - anything but inanimate these even in their present ruin - that cover the walls and ceiling. The chief painters of the Sienese school lent a hand in producing the works I name, and you may complete there the connoisseurship in which, possibly, you will have embarked at the Academy. I say "possibly" to be very judicial, my own observation having led me no great length. I have rather than otherwise cherished the thought that the Sienese school suffers one's eagerness peacefully to slumber - benignantly abstains in fact from whipping up a languid curiosity and a tepid faith. "A formidable rival to the Florentine," says some book - I forget which - into which I recently glanced. Not a bit of it thereupon boldly say I; the Florentines may rest on their laurels and the lounger on his lounge. The early painters of the two groups have indeed much in common; but the Florentines had the good fortune to see their efforts gathered up and applied by a few pre-eminent spirits, such as never came to the rescue of the groping Sienese. Fra Angelico and Ghirlandaio said all their feebler confrères dreamt of and a great deal more beside, but the inspiration of Simone Memmi and Ambrogio Lorenzetti and Sano di Pietro has a painful air of never efflorescing into a maximum. Sodoma and Beccafumi are to my taste a rather abortive maximum. But one should speak of them all gently - and I do, from my soul; for their labour, by their lights, has wrought a precious heritage of still-living colour and rich figure-peopled shadow for the echoing chambers of their old civic fortress. The faded frescoes cover the walls like quaintly-storied tapestries; in one way or another they cast their spell. If one owes a large debt of pleasure to pictorial art one comes to think tenderly and easily of its whole evolution, as of the conscious experience of a single mysterious, striving spirit, and one shrinks from saying rude things about any particular phase of it, just as one would from referring without precautions to some error or lapse in the life of a person one esteemed. You don't care to remind a grizzled veteran of his defeats, and why should we linger in Siena to talk about Beccafumi? I by no means go so far as to say, with an amateur with whom I have just been discussing the matter, that "Sodoma is a precious poor painter and Beccafumi no painter at all"; but, opportunity being limited, I am willing to let the remark about Beccafumi pass for true. With regard to Sodoma, I remember seeing four years ago in the choir of the Cathedral of Pisa a certain small dusky specimen of the painter - an Abraham and Isaac, if I am not mistaken - which was charged with a gloomy grace. One rarely meets him in general collections, and I had never done so till the other day. He was not prolific, apparently; he had however his own elegance, and his rarity is a part of it.
