@st.sisto: The most important detail in this Renaissance fresco is one almost nobody notices. Painted by Piero della Francesca between 1452–1466, The Annunciation is filled with hidden symbolism about Christ’s future sacrifice. From the mathematically perfect architecture to the mysterious wooden log foreshadowing the crucifixion cross, every detail was designed with meaning. The deeper you look into Renaissance art, the more it reveals. #RenaissanceArt #CatholicArt #ChristianArt #PieroDellaFrancesca #ArtHistory
