The daughter of the late shipping tycoon Aristotle Onassis died in Argentina late Saturday, leaving the family fortune to her 3-year-old daughter, Athena.

Her casket was taken early Friday from the Athens First Cemetery to the St. Photini Church in the suburb of Nea Smyrni, where the Mass was celebrated. A heavily overcast sky matched the somber occasion.

Attending the Mass was Onassis' fourth husband, Thierry Roussel, members of the Onassis family and friends in the shipping community.
