7218 Skácel           Discovered 1979 Sept. 19 by J. Květoň at Klet.
Jan Skácel (1922-1989), Czech poet of South Moravian origin, was one of the most beloved Czech poets of the last century. He wrote about human life, love, morals, dreams and nature in poems or just quatrains, as Hope with Wings of Beech shows. Skácel was awarded the German international literary Petrarca-Preis in 1989.
