Statue of Sir John Cass

I noticed this statue yesterday above the entrance to the old London Guildhall University, now home of the Sir John Cass Foundation. I thought the expression on the statue as you look from below was quite interesting. Sir John Cass was a fellow who lived until 1718, who in his will set up a school for boys and girls in Aldgate, and a school in his name carries on today, along with the charitable foundation bearing his name.
