We do not merely study the past: we inherit it, and inheritance brings with it not only the rights of ownership, but the duties of trusteeship. Things fought for & died for should not be idly squandered. For they are the property of others, who are not yet born.

Bezoars And Goa Stones

I just learned aboutbezoars andGoa stones (a man-made form of bezoar). It’s a chunk of aggregated minerals, seeds, piths, and other indigestible material that forms in the intestinal system of animals. People would shave off small bits and add to tea and beverages for medicinal purposes.

The way humans discover things without understanding why they work is endlessly fascinating.

Love this description:

The stones made their way to England as well and an early mention is made in 1686 by Gideon Harvey who was sceptical of the curative value noting that they were confected from a “ jumble of Indian Ingredients ” by “ knavish Makers and Traffickers.’

Chillon Castle (3 of 3)

Chillon Castle , island fortress on Lake Geneva, Switzerland.

The building originally dates to the 11th century, but there’s evidence the Romans had forts on the small island a millennium earlier.

It’s functioned as fort, prison, and summer home to counts and dukes. Added to my one-day-Swiss-vacation list.
