Palantir is a semi rigid ball shape unit originally designed by Melody Pershall.
Palantir tutorial includes full-color pictures and step-by- step instructions to complete the Palantir unit in two sizes. All sizes are based on C&T rings. Knowledge of both byzantine and full persian will be helpful in construction of this unit. 12mm or 8mm rivolis are needed to complete units.
