“While I was thus mutely pondering within myself, and recording my sorrowful complainings with my pen, it seemed to me that there appeared above my head a woman of a countenance exceeding venerable. Her eyes were bright as fire, and of a more than human keenness; her complexion was lively, her vigour showed no trace of enfeeblement; and yet her years were right full, and she plainly seemed not of our age and time. Her stature was difficult to judge. At one moment it exceeded not the common height, at another her forehead seemed to strike the sky; and whenever she raised her head higher, she began to pierce within the very heavens, and to baffle the eyes of them that looked upon her. Her garments were of an imperishable fabric, wrought with the finest threads and of the most delicate workmanship; and these, as her own lips afterwards assured me, she had herself woven with her own hands. The beauty of this vesture had been somewhat tarnished by age and neglect, and wore that dingy look which marble contracts from exposure. On the lower-most edge was inwoven the Greek letter Π, on the topmost the letter θ, and between the two were to be seen steps, like a staircase, from the lower to the upper letter. This robe, moreover, had been torn by the hands of violent persons, who had each snatched away what he could clutch. Her right hand held a note-book; in her left she bore a staff. And when she saw the Muses of Poesie standing by my bedside, dictating the words of my lamentations, she was moved awhile to wrath, and her eyes flashed sternly. ‘Who,’ said she, ‘has allowed yon play-acting wantons to approach this sick man—these who, so far from giving medicine to heal his malady, even feed it with sweet poison? These it is who kill the rich crop of reason with the barren thorns of passion, who accustom men’s minds to disease, instead of setting them free. Now, were it some common man whom your allurements were seducing, as is usually your way, I should be less indignant. On such a one I should not have spent my pains for naught. But this is one nurtured in the Eleatic and Academic philosophies. Nay, get ye gone, ye sirens, whose sweetness lasteth not; leave him for my muses to tend and heal!’ At these words of upbraiding, the whole band, in deepened sadness, with downcast eyes, and blushes that confessed their shame, dolefully left the chamber.” (from the The Consolations of Philosophy by Boethius)
