On the following plate is given the first half of an inscription carved on the sides of stela B from Copan[11].
| The Great Cycle sign is in this instance the 54th Great Cycle. | |
| No. 1. | The Cycle sign with one bar and four dots (5+4=9) above it. |
| No. 2. | The Katun sign with three bars (5+5+5=15). |
| No. 3. | The Ahau sign with the sign for a “full count” in front of it. |
| No. 4. | The Chuen sign with “full count.” |
| No. 5. | The Day sign with “full count.” |
| No. 6. | The day named Ahau with four dots. |
| No. 7. | The month named Yax with two bars and three dots (5+5+3=13). |
The Initial date of this inscription therefore reads as follows:—
| 54th | Great Cycle. | |
| (1) | 9th | Cycle. |
| (2) | 15th | Katun. |
| (3) | “Full count” | Ahaus. |
| (4) | “Full count” | Chuens. |
| (5) | “Full count” | Days. |
| (6) | 4 Ahau (day). | |
| (7) | 13 Yax (month). | |
As a “full count” of days (twenty) is a Chuen, a “full count” of Chuens (eighteen) is an Ahau, and a “full count” of Ahaus (twenty) is a Katun. The foregoing inscription may be read thus:—
The 15th Katun of the 9th Cycle with no Ahaus, Chuens, or days added, begins with 4 Ahau 13 Yax.
