Margherita Colonna
She was born in Palestrina about 1255. Her father, Oddone Colonna, died when she was about two years old. Her mother, who was also named Margherita and who was the sister of Matteo Rosso Orsini and a pious woman, died when Margherita was probably a little over ten years old. Margherita was left in the care of her older brothers.
Stabat Mater (Giovanni Pierluigi da Palestrina)
Palestrina's Stabat Mater appears to have been written for Pope Gregory XIV, who was Pope from 1590 until his death in 1591. Therefore, the work may have been composed during this time– a period which was within the final years of Palestrina's life. Since then, the work was initially guarded closely by the choir for which was written. The first part was performed annually on Palm Sunday at a slower tempo.
