|Namazu-e... Catfish prints|
|Great Ansei Edo Earthquake, 1855|
Following the third of three great earthquakes known collectively as the "Ansei Daijishin" of 1854-55 (Great Ansei Earthquakes-- Ansei was the name of the era, as "Heisei" is now), woodblock prints of the quake destruction were produced. But far more popular were the "Namazu-e", catfish prints, which became a way of venting at the gods (Kashima, who fell down on the job of restraining the catfish),the politicians, and the wealthy (the Namazu qua earthquake became a symbol of the redistribution of wealth-- "Yonaoshi", or 'World Rectification').
Pink Tentacle has a great article with *lots* of prints... go have a look! He's found zillions of beautiful Namazu-e (nice and clear, too).
