Birth
Sky Woman's daughter, grown on the new earth of Turtle Island, gives birth to twin sons. Tellers differ on how she conceives; in many versions, the birth of the second twin, Flint, is unusually difficult and costs her life, which is why Sky Woman raises the boys herself.
Shaping the world
As the twins grow, they set about shaping the young earth, and, in most tellings recorded by Parker and Hewitt, they work in opposite directions. Sapling, also called Skyholder, makes rivers run smoothly, plants bear food, and the land welcome; Flint makes rapids, thickets, and hardship, or in some tellings brings dangerous creatures into being. Neither is purely good or purely evil in the way an outside reader might expect; together they are read by many tellers as accounting for why the world holds both ease and difficulty side by side.
Copying and spoiling
In several of Hewitt's texts, Flint tries to copy what his brother makes and produces something harsher: where Sapling makes useful animals, Flint's attempts turn into dangerous creatures. In Parker's Seneca summary, Sapling (the Good Mind) shapes the first people from clay, is tested by his father before he receives the animals he brings to the earth, and assigns the Thunderer and the winds their work in the world.
An unresolved contest
The brothers eventually contest with each other, sometimes described as a wrestling match or a contest of power, and recorded tellings disagree on how it ends. Some Seneca tellers describe Sapling winning outright; others describe an ongoing, unresolved balance between the two rather than one twin's final defeat. This site does not choose between them.
Where Flint Went
In tellings where Sapling prevails, Flint is not destroyed but withdraws or is confined, often under the earth or to the west, and his influence continues in winter, hard stone, and other difficulties people still face. Parker's summary has the Good Mind confine his brother after their final conflict and later depart along the sky road. The contest is therefore less an ending than an explanation of the world's lasting balance.
