Coins from Frankfurt 1647-1658

I soon became curious as to what kind of money was around during Maria Sybilla's lifetime; the hunt was on!
This coin was minted in Frankfurt in 1647, the year Maria Sybilla Merian was born.  Its denomination is that of an Albus.  Having never heard of that before, I began to research to try to get an idea of how much it was worth at the time.  That, I soon discovered, is practically impossible to do.  Not only were different coins minted in different cities and different areas, but there were also coins that were called by the same name that had a slightly different values.  Throw in exchange rates and it all gets very confusing.  Now add the fact that there is very little written about what things cost back then.  I have no more idea of what it's worth now than I did when I started!
These coins were given to the parents of newborns when the baby was baptized.   The side with writing on it says: "Be true until death and I will give you the crown of life." 
This coin was minted  to celebrate the coronation of Leopold I as Holy Roman Emperor.  The coronation and celebration was held in Frankfurt when Maria Sybilla Merian was eleven years old.  The inscription is in Latin; the date given is Ausust 1, 1658. 
I find it fascinating that these coins are still in existence!

Lantern Bug

On wet sandSide pinnedWings pinned
While Maria Sybilla Merian was in Surinam, South America, she  was given some of these insects in a box.  They are so unusual looking, I just had to see a real one.  Since I haven't managed to get to Surinam and the rainforest there, I bought a Lantern bug ( scientifically known as Fulgora lanternaria ) from the internet!  Then I had to learn how to go about mounting it.  Thomas J Riley, entomologist and photographer, emailed me detailed instructions; and David E. Bowles, entomologist and Professor of Biology, gave me some mounting pins to use; both were very much appreciated!
Since it came as shown in the first picture, it had to be "relaxed" first.  I slit the plastic it came wrapped in to allow moisture in.  Then I placed it in a plastic contained partially filled with wet sand.  On top of that I placed a piece of matboard cut to fit the container.  On went the lid, sealing the bug inside with all that moisture.  And I waited…and waited…and waited.  On the fourth day I took the bug out and carefully took off the plastic it had been shipped in.  I lightly touched the wingtip; it was slightly flexible.  I put it back and closed the lid.  The next day I tried again.  Again I was afraid the bug wasn't damp enough to spread its wings.
Day six.  I did it!  I discovered that the groove I made in the piece of styrofoam was a bit too large there in the middle, so I scooted the bug up.  His peanut shaped protuberance in front of his eyes sticks out over the edge of the styrofoam.  It was actually easy to gently pull the wings into position, place the strips of paper over the wings to hold them down, and pin through the paper to hold the wings in position.
Now I wait some more.  After this unusual bug dries out again, I will mount it in a display case.  I'm ready!  In fact, I'd like to do another one!

Search for the Old City Continues

  This time I had better luck in getting a feel for the size of the old city of Frankfurt am Main.  A wonderful scale model replica of the city is on display in the Frankfurt Historical Museum.  The model, built by brothers Hermann and Robert Treuner were made on a scale of 1:200.  They began working on this in 1926 but were interrupted by the devasting bombing of Frankfurt during WWII which totally destroyed everything.  (Well, everything except for one building–that's all that was left!)  Hermann Treuner finished what he could in 1955.  The model does not show the entire old city because the documentation of how it all looked was gone.  He could only finish what they already had to work with.
  Still, by comparing this model with maps showing the old city, it was much easier to get a sense of the size.  Everything still seemed close and easily within walking distance.
  The city model also showed dramatically how the St. Bartholomew Church (also known as the Dom) rose majestically above the rest of the city.  It's spire could be seen from anywhere in town.  This is the church where Leopold I was crowned Holy Roman Emperor when Maria Sybilla Merian was eleven years old.
