Author’s Notes for “Shipbirth”
Second installment of Author’s Notes, this time for “Shipbirth” (in the February 2011 issue of Asimov’s).
Hmm, first off, this one requires an apology: the tonalli, the life-force according to the Aztecs, is of course not located in the heart but in the head. I realised I made this mistake only after the issue of Asimov’s went to the printers, when it was already too late to correct this.
The Aztec medicine system was fairly complicated, admitting the presence of no less than three entities in the body: the tonalli (in the head), which is the lifeforce, and, when chased out of the body by a fright or a spell, can result in catatonia; the teyolia (heart), which is the closest to what we think of as a soul (in particular, it’s the part that survives into the various afterlives), and the ihiyotl (liver), which is more numinous. See Mexicolore for more information, if you’re interested.
