According to theologian Lisa J. Schwebel, claims of the miracle present a number of difficulties. Schwebel states, "not only did all those present not see the phenomenon, but also there are considerable inconsistencies among witnesses as to what they did see". Schwebel also observes that there is no authentic photo of the solar phenomena claimed, "despite the presence of hundreds of reporters and photographers at the field" and one photo often presented as authentic is actually "a solar eclipse in another part of the world taken sometime before 1917". There is some evidence to the effect that the miracle was expected by witnesses. The witness Joaquim Gregorio Tavares, who was present at Fatima on October 13th, states, "We must declare that, although we admit the possibility of some miraculous fact, we were there while having in mind conversations we had earlier with cool-headed persons who were anticipating some changes of colour in the Sun" The villagers in Alburitel were preparing for a Sun miracle too. According to Maria do Carmo, "It was anticipated that the miracle would involve the stars". This is likely due to the fact that in the months of July, August and September people at Fatima claimed the Sun's light dimmed and the sky became dark enough for stars to become visible. This was denied too by many witnesses from the previous months. She also states that on the morning of October 13th, "the people of Alburitel were darkening bits of glass by exposing them to candle-smoke so that they might watch the Sun, with no harm to their eyes."
