Viewers

Diachronic Layered Viewer

The diachronic layered viewer contains the entire manuscript of the St. Chad Gospels, with every available version of every page. The viewer allows the user to navigate to any page of the manuscript, and then to compare any versions with each other. This can be used to discover and illustrate ways in which the physical page has changed or degraded over time.

Diachronic Viewer (prototype)

The Diachronic Viewer shows an illustrated page from the Gospel of Matthew of the St. Chad Gospels. The first thumbnail on the left shows a high-resolution color image taken in 2010 with permission from the Lichfield Cathedral in England. The following thumbnails allow you to select images of the same page from previous years. Select the layers you wish to view—either on its own or in comparison with another—by clicking on the thumbnail.

Modal Viewer (prototype)

This viewer exhibits a page from the St. Chad Gospels which shows both Latin text from the Gospel of Matthew as well as the oldest written version of Welsh known to be in existence. The first thumbnail on the left shows a high resolution color image taken in 2010 with permission from the Lichfield Cathedral in England. The following thumbnails allow you to select images of the same page taken under different spectrums of light and then combined using different mathematical algorithms. The layers allow you to compare what can be seen under various spectrums of light. Select the layers you wish to view—either on its own or in comparison with another—by clicking on the thumbnail.

Code Packages

To encourage open access, we have made our code packages available to the public.

registration-toolkit

The registration-toolkit contains the source code for the registration process, including all related scripts. These were used to create the comprehensive registered set of images of the St Chad Gospels manuscript.

layered-viewer

The source code for the layered viewer, which is hosted at infoforest.vis.uky.edu.

jsRegistrationViewers

The source code for all FoLIO prototype viewers. It also houses the JavaScript Client API for CITE servers, enabling quick and easy development of JavaScript applications that require CITE images and resources.

multispectral-toolkit

A collection of shell scripts used to simplify and automate the processing of large multispectral datasets.

gci-xmlbuilder

A Python-based GUI application for creating and editing Google Cultural Institute-compliant XMLs.

Datasets and Image Archives

Internet Archive

The registered versions of the St Chad Gospels manuscript, as well as the version imaged in 2010, are hosted with the Internet Archive. The original, full resolution tiff images for each page are available, as well as a variety of other derived formats. The diff images, landmark files, and transform files are also stored for each page of each version, indicating how they were altered by the registration process.

Furman Data Archive

Furman University assembled a catalog of the Lichfield data, which is available for browsing.
