The Great Seal of the State of Ohio was first depicted in 1803 and was often reconfigured until the present image was sanctioned by the Ohio General Assembly in 1967 and modified in 1996. Its design drew inspiration from the hills before the viewer, including Mount Logan, as seen from Thomas Worthington's estate, Adena, now a state memorial. The 1803 law prescribed a sheaf of wheat to represent Ohio's agricultural roots and a bundle of seventeen arrows to symbolize Ohio's place as the seventeenth state in the Union. The sun's thirteen rays represent the thirteen original colonies, and the Scioto River flows between the hills and the cultivated fields in the foreground. Tradition attributes the design to the cooperative vision of Thomas Worthington, the first U.S. Senator and "Father of Ohio Statehood," Edward Tiffin, Ohio's first governor, and William Creighton, Ohio's first secretary of state, who after an all-night meeting at Adena viewed the sun rising over Mount Logan and chose the scene for the state seal. Much of the land illustrated in the Great Seal of the State of Ohio now comprises Great Seal State Park.
