Giordano Orsini

Giordano Orsini, called del Monte (died 1367), was a Roman baron of the Orsini di Monterotondo branch and lord of Monterotondo and Marino. He sat as senator of Rome repeatedly from 1339 to 1353, and in 1341 he crowned Petrarch with the laurel on the Capitol.

When Cola di Rienzo seized power in 1347, Giordano was almost the only Roman baron to back the tribune: he knighted him, was made console and patrician, and in the street fighting led his cavalry against the Colonna. He abandoned Cola in 1348 and was besieged by his troops at Marino.

From 1352 he served Cardinal Gil de Albornoz as rector of the Patrimonio, campaigning against the prefect Giovanni di Vico; he had forced Vico's surrender at Vetralla in 1347. He headed the Monte Giordano line, which tradition names as the source of the name of the Roman hill.
