These concordances provide a cross-reference for the three main
Maya glyph-classification systems in current use:
(i) the MHD codes, used in the
Maya Hieroglyphic Database
to encode a substantial portion of known Maya inscriptions;
(ii) the
TWKM codes,
a recent rework and extension of T-numbers
by the Bonn University TWKM Project;
and
(iii) the well-established, but outdated,
Note: a) This is a preliminary release of these concordances. There are still some rough edges, especially in the CMGG Concordance,
but we felt it would be useful to publish them anyway. Updates will be made as time allows;
b) These concordances aim to reflect up-to-date versions of the MHD and
TWKM Catalogs but both systems are dynamic and so there is always the possibility
of some lag before changes in them are reflected here.
Click/Touch the buttons below to access the concordances. Each will pop up in its own window, which will be of the minimum width needed to see all the columns. If your screen is not wide enough, there will be a scrollbar at the bottom. You can zoom out (Ctrl-"-" or Ctrl-mouse-scroll) to make more of it fit. and/or you can resize the window to your liking. If you open multiple concordances, the windows will stack, slightly offset from each other; you can of course reposition, resize and/or minimize them as you want. The concordances are complex, lengthy tables with lots of graphics, so may take a few seconds to load.

Lists all TWKM signs (as of 2026-01-31) with their corresponding MHD codes,
related T-numbers and relevant CMGG entries.
Some MHD codes, T-numbers and CMGG entries do not appear in this concordance because they do not all correspond to TWKM signs. |
Lists all MHD codes (as of 2026-01-12) with their corresponding TWKM signs,
related T-numbers and relevant CMGG entries.
Some TWKM signs, T-numbers and CMGG entries do not appear in this concordance because they do not all correspond to MHD codes. |
(COMING SOON) Will list all T-numbers and related TWKM and MHD codes. Meanwhile, T-numbers in current use can be found in the TWKM and MHD concordances. |
Lists all CMGG syllabograms and logograms (as of 2025-11-15)
with their corresponding TWKM signs, MHD codes and related T-numbers.
Some MHD codes, TWKM signs and T-numbers do not appear in this concordance because they do not all correspond to CMGG entries. |
