IX

Girolamo Melzi had once belonged to the court of the Sforzas, but on the death of his young wife in 1494 he had retired to his lonely villa at the foot of the Alps, a few hours' journey from Milan. Far from the noise of the world, he lived the life of a philosopher, gardening with his own hands, and devoting himself to music and to the study of the occult sciences. Some said he was an adept in black magic, accustomed to call up the shade of his lost wife from the lower world. The mathematician, Fra Luca Pacioli, and Sacrobosco, the alchemist, often visited him, and whole nights were spent in argument about Plato's ideas, and the laws of the Pythagorean numbers which governed the music of the spheres. But Melzi found his chief pleasure in the visits of Leonardo, which were not infrequent, as the works on the Martesana Canal often brought him to the vicinity.

Vaprio was situated on the left bank of the Adda; and the canal, skirting the villa garden, ran for a certain distance parallel to the river, the course of which was just here obstructed by rapids. All day the roar of the cataract made itself heard, loud as the billows of the sea surf. Free, wild, storm-tossed, untamed by man, the Adda hurled its green waves between winding precipitous banks of yellow sandstone. By its side, the same cold, green, mountain water swam noiselessly by within the straight-drawn confines of the canal; smooth as a mirror, calm, slow, submissive and subdued. The contrast delighted Leonardo, and seemed to him of pregnant meaning. Which of the two streams was the more beautiful—the Martesana, his own creation, the work of human intelligence and will, or its elder sister, the foaming Adda, savage, threatening, superb in its untrammelled freedom? He understood each, sympathised with each, and loved them with equal love.

From the upper terrace of the villa garden was a wide prospect of the immense Lombard plain, one vast and smiling garden. In the summer the fields were rank with verdure; hay scented the air; the wheat and the maize grew so tall as to overtop the vines; ears of corn kissed the pears and the apples, the cherries and the plums. The hills of Como rose dark towards the north; above them towered the first spurs of the Alps; higher still the snow-clad summits glowed in the sunset gold.

Fra Luca and Messer Galeotto Sacrobosco, whose cottage by the Porta Vercellina had been destroyed by the French, were both at the villa when Leonardo arrived; but he kept himself apart, preferring solitude. He conceived, however, a great fondness for the company of Francesco, his host's little son.

Timid and shy as a girl, the boy at first stood in great awe of the painter; one day, however, he came into his room at a moment when Leonardo, studying the laws of colour, was experimenting with coloured glass. He pleased the child by letting him look through the different pieces, yellow, blue, purple, or green, which gave a fairy aspect to familiar objects, and made the world seem now smiling, now frowning, according to the colour of the glass. Another of Leonardo's inventions proved very attractive. This was the 'Camera obscura,' by means of which living pictures appeared on a sheet of white paper; and Francesco saw the turning of the mill-wheel, the swallows circling round the church, the woodcutter's grey donkey with his load of faggots stepping daintily along the miry road while the poplars bowed their heads under the breeze. Still more fascinating was the weather-gauge: a copper ring, a small stick like the beam of a balance, and two little balls, the one covered with wax, the other with wadding. When the air was saturated with moisture the wadding grew heavy, and the little ball, falling down, inclined the beam till it touched one or other of the divisions marked on the copper ring. The degree of damp could thus be accurately measured, and the weather predicted for two or three days. The little boy constructed a similar apparatus for himself and was jubilant when the prophecies were fulfilled which he had deduced from its variations. Francesco went to the village school where he was taught by the old prior of the neighbour convent. The dog-eared Latin grammar and arithmetic primer were odious to him, and he learned but slackly. Leonardo's lore was of a new sort, pleasant to the child as a fairy tale. The instruments for the study of optics, acoustics, hydraulics, were to him new and magical toys, nor was he ever tired of hearing the painter's talk. Fearing ridicule or suspicion, Leonardo spoke but cautiously with adults; to Francesco he talked with the utmost frankness and simplicity. He not only taught the child, but learned of him. Paraphrasing the text of Holy Writ, he told himself—'Except ye be converted and become as little children, ye shall not enter into the kingdom of knowledge.'

It was at this time that he was writing his Book of the Stars. On March evenings, when in the still chilly air there was a waft of spring, he would stand on the roof with Francesco, watching the tide of stars and sketching the spots on the face of the moon. Then rolling a piece of paper into an inverted cone, he bade the child look through the aperture at the end, and Francesco saw the stars robbed of their rays, and like bright, round, infinitely minute globules.

'Those globules,' said Leonardo, 'are of great size, many of them a hundred, nay, a thousand times larger than our earth, which, however, is not less beautiful nor more contemptible than they. The mechanical laws which obtain in our world, and which have been discovered by human sagacity, guide also those stars and suns.'

'What is there beyond the stars?' murmured the child.

'More stars, Francesco; worlds which we cannot see.'

'And beyond those?'

'Yet others.'

'But at the end, at the very end?'

'There is no end.'

'No end,' cried the boy, and Leonardo felt the trembling of the little hand within his own. The child's face had grown pale.

'Then where—where,' he said slowly, 'where is Paradise, Messer Leonardo, and the angels, and the saints, and the Madonna, and God the Father who sits upon the throne with God the Son and the Holy Spirit?'

The teacher would have liked to answer that God was everywhere; in the grain of sand no less than in the celestial globe; in the hearts of men no less than in the outside universe. But fearing to disturb the simple faith of the little one he held his peace.

With the first budding of the trees, the painter and the child spent whole days together in the garden or in the neighbouring woods watching the reviving of life in the vegetable world. Sometimes Leonardo would draw a flower or tree, trying to seize the living likeness as in the portrait of a man; that unique particular aspect of his model which would never be repeated. He taught Francesco how the rings seen in the wood of the trunk reveal the age of the tree; and how the thickness of each ring shows the amount of moisture in the year when it was formed; how the core of the trunk is always on the southern side, which has had the most of the sun's heat. He told how in the spring-time the sap, gathering between the inner green of the trunk and the outer bark, thickens and expands and bursts the bark; how, if a branch is cut, the vital power draws an abundance of nutritive juices to the wounded place, so that the bark thickens and the wound is healed; yet its mark remains because the abundance of the nutritive juices has been too great, and has overflowed and made lumps and knots. Always he spoke of nature dryly and with apparent frigidity, seeking only scientific accuracy. With passionless exactitude he defined the tender details of the action of the spring upon the life of plants, as he would have spoken of the performance of a machine. He showed from abstract mathematics the wonderful laws which shape the needles of pine-trees and the facets of crystals. Yet for all his coldness and impartiality, the child discerned his love for all living things, for the withered leaf no less than for the mighty boughs which spread suppliant arms to their great lord, the sun. At times, in the depth of the forest, he would pause and note smilingly how under last year's withered leaves still hanging on the branches, green shoots were sprouting to oust them from their place; how the bee, weak from her winter torpor, could scarce crawl into the snowdrop's cup. In the great stillness Francesco could hear the beating of his friend's iron heart; timidly he would raise his eyes to the Master. The sun shining athwart the branches lit up his long curling hair, flowing beard, and overhanging brows, and surrounded his head with a halo: he seemed like Pan himself who listens to the growing of the grass, the murmuring of spring below the earth, the mystical forces of awakening life. To Leonardo all things lived. The world was one great body, like the body of man, who himself is a little world. In the dewdrops he saw the similitude of the watery sphere which surrounds the earth. The cataracts of the Adda near Trezzo gave him occasion to study the cascades and whirlpools of rivers which he compared to the twisting of a woman's curls. Mysterious resemblances attracted him, concords in nature's harmony like voices answering each other from distant worlds. Inquiring into the origin of the rainbow, he noted that the same prismatic colour is seen in the plumage of birds, precious stones, in the scum on stagnant water, in old dulled glass. In the patterns on frosted window-panes, he found a resemblance to living leaves and flowers, as if nature in this world of frozen crystal had seen prophetic visions of the coming spring. At times he felt himself drawing near new realms of knowledge, perhaps to be entered only by men of ages to come. He used to say about the attractive powers of amber:—

'I see not the mode by which the human mind shall apprehend the mystery. These powers of the magnet and the amber are among those occult forces which are as yet unrevealed.'

And further—

'The world is full of countless possibilities of which yet there has been no experience.'

One day, a certain Messer Guidotto Prestinari, a poet from Bergamo, came to the villa. Offended with Leonardo, who did not sufficiently praise his verses, he began a discussion on the comparative excellence of poetry and painting. Leonardo spoke little, but the fury with which Messer Guidotto assailed his art at last amused him and he said, half jesting:—

'Painting is higher than poetry, inasmuch as it reproduces the eternal works of God and not human inventions, to which the poets, at least of our day, are too apt to confine themselves. They depict not, but describe, borrowing all they have and trading with each other's wares. They but put together and combine the refuse of knowledge. They may be compared to the receivers of stolen goods....'

Fra Luca, Messer Galeotto, and Melzi himself cried out; but Leonardo had now warmed to the subject and cried:—

'The eye gives a more complete knowledge of nature than the ear! Things seen are less to be doubted than things heard. Painting, which is silent poetry, comes nearer to positive science than poetry, which is invisible painting. Words give but a series of isolated images following one another; but in a picture, all the forms, all the colours appear synchronously, and are blended into a whole, like the notes of a chord in music; and thus both to painting and to music a more complex harmony is possible than to poetry. And the richer the harmony, the richer is that delight which is the aim and the enchantment of art. Question, say, any lover, whether he would not rather have a portrait of his loved one than a description in words of her countenance, though it were composed by the greatest of poets?'

This argument provoked a smile, and presently Leonardo continued:—

'Hear a narrative from my own experience. A certain Florentine youth fell into such a longing for the face of a woman whom I had painted in one of my sacred pictures, that, having bought it, he cancelled all the signs of its religious character, so that he might kiss his adored one without fear or scruple. But soon the voice of conscience overcame the passion of love, nor could he recover his tranquillity of mind till he had removed the picture from his dwelling. Think ye, O poets, that with your words you could rouse a man to like vehemence of desire? Believe me, Messeri, I speak not of myself, for I know how greatly I fall short, but of that painter who attains to the perfection of his art. He is no longer a man; rapt in the contemplation of divine and eternal beauty, or turned to the study of monstrous forms, grotesque, pathetic, terrible, he can comprehend and give shape to all; he is a sovereign—a god.'

Many such ideas Leonardo had inscribed in his note-books; and Fra Luca urged him to order his manuscripts and give them to the public. He even offered to find him an editor. Leonardo, however, refused, and remained firm in his resolution that he would publish nothing. Yet all his writings were couched in the form of address to a reader; and at the commencement of one of his diaries he apologised in these words for the disconnected style and frequent repetitions:—

'Blame me not, O reader, for the subjects are numberless and my memory is weak, and I write at long intervals in different years.'
