Себастьяно дель Пьомбо
The "Birth of the Virgin" was eventually begun by Sebastiano del Piombo using an unusual technique, oil on peperino stone blocks. This was invented by him and greatly admired by his contemporaries. The mural was left unfinished by Sebastiano in 1534 and it was completed by Francesco Salviati by 1554. The upper part with the figure of the Holy Father and the angels is mainly Salviati's work.
