Old Coaly
（重定向自Coaly）
Old Coaly (1855 – January 1, 1893) was a mule who helped to build the original Old Main building on the campus of the Pennsylvania State University and gained fame as an early Penn State mascot.
Born in Kentucky in 1855, Coaly came to Pennsylvania in 1857 with his owner, Piersol Lytle, whose son Andy was among the workmen hired to construct Old Main. Coaly was used primarily to haul limestone blocks to the construction site from a quarry located on what is today a part of the Old Main lawn, near the intersection of College Avenue and Pugh Street. A plaque now marks the quarry's location.
