Mariano Cardinal Rampolla del Tindaro (1843-1913) was titular archbishop of Eraclea (consecrated by Cardinal Howard in 1882) and nuncio to Spain from 1882 to 1887, before he received the red hat in 1887 with the title of S. Cecilia in Trastevere. He was Cardinal Secretary of State from 1887 to 1903, President of the Pontifical Biblical Commission from 1902 to 1908 and Archivist of the Vatican Secret Archives from 1912 until his death.
This is an official portrait on which he looks like a person with which you'd rather not have any grave misunderstanding.
This portrait photo is notable for its solemn mood and what could possibly be the shiniest silk-fascia ever to be photographed.
Cardinal Rampolla is buried in S. Cecilia in Trastevere. His tomb is absolutely stunning, as you can see.
