The EarthCycles Calendar is a project by artist and inventor Russell Maier. The project merges Russell's academic background in western Philosophy with his experience of Igorot and kincentric cultures in Asia and America.
The EarthCycles project is inspired by Russell's painting of the colorful seasons of the Bulkley Valley and later his time in the ancestral territory of the Igorots. Underlying the calendar is the philosophy of regenerative ethics developed by Russell and Banayan Angway. See the Tractatus Ayyew for the full Earthen ethic theory-- in particular their observation of cyclical synking in kincentric cultures.
