There was a gentle twilight, the coolness of evening barely perceptible. Side by side, their elbows resting on the balcony, Maria Sara and Raimundo Silva watched in silence, conscious of each other's presence, the arm of the one feeling the arm of the other, and, little by little, the warmth of their blood. The pounding of Raimundo Silva's heartbeat echoed in his ears, that of Maria Sara threatened to shake her from head to foot. His arm drew closer, hers remained where it was, expectant, but Raimundo Silva dared go no further as fear crept in, I might make a mess of things, he thought, he could not see clearly, or did not want to, what was there to mess up, but this very uncertainty only served to increase his panic. Maria Sara could feel his entire being recoil like a snail withdrawing ever deeper into the protection of its shell, and she remarked cautiously, It's a nice view. The first lights appeared in the windows where the last rays of daylight still lingered, the street-lamps had just come on, someone in the nearby Largo dos Lóios spoke in a loud voice, someone replied, but the words were incomprehensible, Raimundo Silva asked, Did you hear them, Yes, I did, It was difficult to make out what they were saying, The same here, I didn't understand a word they said, We'll never know to what extent our lives would change if certain phrases, heard but elusive, had been understood, Much better, in my opinion, to start by not pretending that we did not understand those other words which were clear and direct, You're quite right, but there are some people, the dreamers, who prefer doubt to certainty, who are much less interested in the object than in its traces, in the footprints in the sand rather than in the animal that left them behind, You are clearly one of them, Up to a point, although I must remind you that it was not my idea to write this new history of the siege, Let's say that I sensed I had the right person before my very eyes, Or that, wisely, you prefer not to be responsible for his dreams, Would I be here if this were true, I suppose not, The difference being that I do not look for footprints in the sand, Raimundo Silva knew that he did not need to ask what it was that Maria Sara was looking for, now he could put his arm around her shoulders, as if unintentionally, a simple gesture, nothing other than fraternal for the moment, allowing her to react, perhaps gently relax her body, perhaps, as one might say, curl up, letting her body curve ever so slightly to one side, her head a trifle bent, awaiting the next gesture. Or she might become tense, protesting silently, anxious that he should see that it was still too soon, So when, Raimundo Silva was asking himself, forgetful of the fear he had felt, After what we've just said, what we've explicitly promised each other, the logical thing would have been, at least, to embrace and kiss, yes, at the very least. He straightened up as if suggesting that they should go back inside, but she continued to lean over the balcony, and he asked her, Don't you feel cold, No, not at all. Fighting back his impatience, he went back to his former position, without knowing what he could talk about, perversely imagining that she was amusing herself at his expense, it was all so much easier when he telephoned her at home, but he could not very well say to her, Go home and I'll call you. Then it occurred to him that he might get out of this embarrassing situation if he were to touch on some neutral topic, That building over there occupies the very spot where one of the towers defending the gate in this locality once stood, you can still see the markings on the ground, And the other tower, where was that, for there must have been two, Right here, where we are, Are you sure, Not absolutely sure, but there is every indication that I'm right, considering what we know about the former plan of this section of the walls, Well then, here on this tower, what are we, Moors or Christians, For the time being, Moors, we're here precisely to prevent the Christians from entering, We won't succeed, nor will it be necessary to await the end of the siege, have you seen the tiled panels depicting the miracles of St Antony at the entrance to the street, Abominable, You mean the miracles, No, the tiles, Why is this street called the Milagre de Santo Antonio, when on the panels alone there are three, I can't answer that, perhaps the saint worked a special miracle for the city fathers, Milagres de Santo Antonio would certainly sound nicer, but the one thing we mustn't do is to imagine that St Antony might have helped with the conquest of Lisbon in any military sense for he wasn't even born then, Two of the miracles on the panels are familiar, the apparition of the Child Jesus and that of the broken pitcher, the third one I don't recognise, there's a horse or a donkey, I didn't pay much attention, It's a donkey, How do you know, I have it here in a book, an old manuscript dating from the eighteenth century which describes all the miracles including this one, Tell me about it, You'd better read it for yourself, Another time, When, I can't say, tomorrow, after tomorrow, one day. Raimundo Silva took a deep breath, he could not pretend that he had not understood these words and he swore in his heart that he would definitely remind Maria Sara of them, as a definite promise demanding to be fulfilled. He felt so happy, so relaxed and free, that without thinking, he placed his hand on her shoulder and said, No, I'll read you the story about the donkey, come inside, Is it long, Like any story it can be told in ten words, or a hundred, or a thousand, or never end.
