Leonardo da Vinci's Apostle Jacobus Sforza Castle Key Ring

Sketch of an Apostle's Head and Architectural Study (c. 1494-1498) by artist Leonardo da Vinci (1452-1519) is a vintage Renaissance Era fine art religious portrait painting. A drawing featuring the head of an apostle, Jacobus Maior study on the "Last Supper" looking down and an architectural drawing of the Sforza Castle. Sketch from one of Leonardo da Vinci's many journals. Leonardo kept a series of journals in which he wrote almost daily, as well as separate notes and sheets of observations, comments and plans which were left to various pupils and were later bound. Many of the journals have survived to illustrate Leonardo's studies, discoveries and inventions. Most of the journals were written backwards in mirror script. His journals were later published, 165 years after his death.
