If you get a retrieval error (signified by a never-ending 'Retrieving data...' notice) AND you want to help me figure out the problem, do this:

If the problem is with a place (in this case, the place is Lyktos), go here:
http://tomcat-stable.hcmc.uvic.ca:8080/myths/apps/mom/site/helpers/place.xql?id=lyktos
You should get back info on the place Lyktos in XHTML format. Change the xml:id to get a different place.

There are similar tools for each data type:
http://tomcat-stable.hcmc.uvic.ca:8080/myths/apps/mom/site/helpers/character.xql?id=hercules
http://tomcat-stable.hcmc.uvic.ca:8080/myths/apps/mom/site/helpers/group.xql?id=argonauts
http://tomcat-stable.hcmc.uvic.ca:8080/myths/apps/mom/site/helpers/event.xql?id=event_3

For each one, you need to provide the xml:id of the problematic entry (e.g. hercules, argonauts, and event_3).

In the case of Lyktos, and at the time of writing, the response was:
