I just read an interview with distinguished British art historian John Boardman made for CBS BNET a couple of years ago. Among other things, Boardman tells about his experience of once having attended one of classical archeologist John D. Beazley‘s (a specialist on Athenian vase painting) lectures:
By spending the entire hour analysing the painting of a single vase, he taught us how to look at an object properly.
There seems to be something lost when we put our artefact collections on the web — it makes slow attention more difficult.
