Caravaggio

Saw this in the news… lost 1600s era painting going to auction. What struck me is that the sword to my eye does not look at all like the European swords of the time. It looks like a ken of some sort. It appears to have a hamon on it and a clearly defined shinogi and maybe a European hilt added to it.

No other content here, just a hmm moment.

The item in question and what it makes me think of:

The sample ken here is quite a bit longer (93cm) than the one being used in the picture. It is a prewar Kokuho which is now Juyo Bunkazai and possibly Naminohira school.
