In Annunciation (Correggio), how is the History discussed?
It was originally painted on the wall of the church of San Francesco in Parma. Its style allows it to be dated to the 1520s, shortly after Correggio finished the frescoes on the dome of the church of San Giovanni Evangelista and just before he began those on the dome of Parma Cathedral. The figure of Gabriel on a cloud with his robe blown in the wind is reminiscent of Correggio's work on these other two frescoesOn San Francesco's demolition in 1546 was moved to another location, where it was seen by Vasari:Also in the same city (Parma), in the church of the Frati de' Zocoli di S. Francesco, can be seen an Annunciation in fresco, which is so fine that when they demolished its original home, the monks placed iron bars behind that section of wall, cut it away little by little and moved the section of wall to another safer position in the same convent. 
It was later moved a second time, to the Annunziata church in Capo di Ponto.
