Picasso's Full-Story

Picasso showed a passion and a skill for drawing from an early age; according to his mother, his first words were “piz, piz”, a shortening of lápiz, the Spanish word for ‘pencil’. From the age of seven, Picasso received formal artistic training from his father in figure drawing and oil painting. Ruiz was a traditional, academic artist and instructor who believed that proper training required disciplined copying of the masters, and drawing the human body from plaster casts and live models. His son became preoccupied with art to the detriment of his classwork.

 The family moved to A Coruña in 1891 where his father became a professor at the School of Fine Arts. They stayed almost four years. On one occasion the father found his son painting over his unfinished sketch of a pigeon. Observing the precision of his son’s technique, Ruiz felt that the thirteen-year-old Picasso had surpassed him, and vowed to give up painting.
