Trecena (13-day period) Mazatl
The thirteen day period (trecena) that starts with day 1-Mazatl (Deer) is ruled by Tepeyollotl, the Heart of the Mountain, the Jaguar of Night, lord of the animals and darkened caves. Tepeyollotl is Tezcatlipoca disguised in a jaguar hide, whose voice is the echo in the wilderness and whose word is the darkness itself, calls to the heart in the voice of the conch. These are 13 days associated with the hunt: whether one is the hunter or the game, this trecena reminds us that our lives are determined by the act of stalking. The arts of tracking and back-tracking, of spotting and camouflaging, of following tracks and covering tracks, rule our lives to the degree that we master them. These are good days to study the routines of others; bad days to keep to your routines.
