From his Wikipedia article:

"Aged 16 he made his first sexual conquest with a young Norwegian tourist and embarked on a path of debauchery from which he would never deviate."

"Modigliani had a turbulent 35 year existence, he battled childhood illness and family depression, seduced a phalanx of models and artists and fathered at least three children before the drugs and alcohol which fired his creativity ultimately ended his life in a squalid, untidy flat."
