Leonardo Da Vinci was left-handed. That's probably why he wrote backwards from right to left to avoid smudging ink on his hand as he made notes on his latest works and visionary discoveries. Words could only be read with the help of a mirror making it taxing for anyone but himself to quickly decode his handwriting. There are many theories exploring the reason why he kept using "mirror writing" in all his manuscripts. Some historians say that he was trying to make it more challenging for people to steal his ideas while others claim that it was a clever attempt to hide scientific findings from the intolerant Roman Catholic Church of the Renaissance. Whatever the logic behind this, the constant association with mirror writing and studies on the human body anatomy, made him one of the most enigmatic figures of his and then of our century. This biography investigates Leonardo and his different roles from anatomist to inventor, architect, painter, rumoured to be templar and scientific pioneer. Despite leaving several of his works incomplete, Leonardo managed to influence generations of artists and still today remains a highly regarded figure in both the artistic and scientific sector.
