Washington and its Western allies decry human rights abuses while arming and shielding Israel, turning contradiction into policy, argues RAMZY BAROUD
LEONARDO DA VINCI was born 570 years ago, on April 15 1452 near the village of Vinci, from which he takes his name.
His mother Caterina was a servant, his father, a professional notary, with whom he was living by 1457 and later with his paternal grandfather. It was during the seven years with his grandfather that Leonardo learned to read, write and calculate.
He never learned Latin, Greek or higher mathematics. Instead, he took up an apprenticeship and ended up in the workshop of a master painter in Florence, which in the 15th century, like much of Italy, was a violent place, where rival merchant dynasties fought each other for power.
