Lenardus Vincis working in Athens publishes a work called "Principia Naturalis". The work is a mathematical treatment of forces including a force called gravitation. Lenardus has developed a new branch of mathematics in the process called "integration". He is an introverted genius as never seen before. Previous geniuses excelled in discourse and social graces. Lenardus is the opposite: a lone figure hardly noticing people around him. But the impact of his work is such that aspiring geniuses start to imitate him. Much later the date of publication will be called the beginning of science.
