Very long ago, I published a paper based on data from my dissertation, a small corpus of ancient sculpture on which one or more crosses had been carved or incised somewhere on their body. I have recently posted an update to this corpus on my Academia page, including the above naiskos in the very nice Patras Archaeological Museum that has no less than three crosses (can you spot them all?). Many thanks to Eirini Chioti for the reference to its publication. There are some further close-ups on Flickr, if you like that sort of thing.
