You have probably heard of the little pictograms that appear on many (though not all) corners in the Centro Historico in Merida. As the story goes, these were used to mark intersections in the past to help the citizens and visitors of old who could not read figure out where they were. Rather than tell someone to "meet me at the corner of Calle 68 y Calle 51," for example, you might say, "meet me at the corner of the Lighning" ("el Rayo"). [Disclaimer: the sign of El Rayo is not at C. 68 y C. 51...this is for illustration only!]
Often, the subject of the pictogram is clear, and it does exactly what it was intended to do. This one marks the corner of "the Cardinal." The one below is "the Pearl."
A simple walk through the historic district can turn into not only a visual treasure hunt, but also a bit of a multi-cultural puzzle as you try to figure out what the signs mean.
For example, this one is "the Lark"...simple enough with a little electronic translation.
Google Translate didn't help too much with this one, though, as it kept insisting that "La Tucha" meant "the Tuch," whatever that is. A little more searching turned up a reference noting that, in the Yucatan, "La Tucha" is also a female monkey. So now that one makes sense too.
