## Dataset Creation

### Source Data

The original source for the images and transcriptions is:
* **Source Manuscript:** *Gwalther, Rudolf: Lateinische Gedichte. Zürich, 1540-1580. Zentralbibliothek Zürich, Ms D 152.*
* **e-manuscripta Reference:** [https://doi.org/10.7891/e-manuscripta-26750](https://doi.org/10.7891/e-manuscripta-26750) (Public Domain Mark)

### Ground Truth Creation Process

1.  Initial data was collected from e-manuscripta (150 images and corresponding transcriptions by Peter Stotz).
2.  8 images were removed due to excessive corrections or vertical text.
3.  The remaining 142 images were uploaded to the Transkribus platform.
4.  Line recognition was applied, and the text lines were manually copied into the recognized line boxes.
5.  Minor corrections were made for inconsistencies in punctuation and capitalization.

### Creators

The dataset creators are: **Peter Stotz** and **Phillip Ströbel**.

## License

The license is listed as **Other (Open)** on Zenodo. Users should confirm the specific rights from the underlying manuscript source (Public Domain Mark via e-manuscripta).
