Heptagon = 7 sided polygon. To create this Venus design (goddess of fertility), draw circle 1-49 and connect numbers using the ancient mathematicians Magic Square of Venus - outlined below (each line adds up to 175). There are 7 rows with the first row using numbers 22, 47, 16, 41, 10, 35, 4... second row: 5, 23, 48, 17, 42, 11, 29... third row: 30, 6, 24, 49, 18, 36, 12... fourth row: 13, 31, 7, 25, 43, 19, 37... fifth row: 38, 14, 32, 1, 26, 44, 20... sixth row: 21, 39, 8, 33, 2, 27, 45... seventh row: 46, 15, 40, 9, 34, 3, 28.
