A bit far-fetched to link this book to the current COVID crisis, but I actually read it a few month ago and really enjoyed it! It's obviously very specific from the point of view of an old European intellectual and filled with nostalgia, but a fascinating read nonetheless, with some great portraits of famous artists from his time.
His rant on passports feels very relevant in these times of ever decreasing personal freedoms and privacy. Hard to imagine the Habsburg empire was actually not that long ago.
