Interior Work Is Starting to Begin at MMA Research Center

Jascin N. Leonardo Finger • Sep 09, 2015

The photograph you see below is the interior south wall of the MMA Library/EcologyLab. The patchwork you see is the terracotta tiles that make up the supporting walls of the building – there is about an inch of stucco on the exterior and a half an inch of lime plaster on the inside walls and that’s it. Those ridges you see are actually the terracotta tiles which make up the structural walls of the building.   When built in the early 1930s, about three coats of a lime plaster were placed on the terracotta and then tempera paint which is the more yellow looking finish you see in areas where the plaster did not fail.   If not for some leaks about a decade or more ago, the plaster would not have failed because everywhere else in the Wing the plaster is in excellent condition – you can’t beat lime plaster!

But due to the damage from the leaks, the lime plaster had blistered and pulled from the terracotta so we called in Pen Austin, an island mason who specializes in traditional methods of mortar, paint finishes, and plaster and who has completed work on the Mitchell House.   Her work on the Science Library is partially Community Preservation Act funded – it became a bigger project because of the work that was completed on the outside of the building.   We had the right woman – and her team – on the job and they completed the plaster work in about a week.   It will take about a month for the lime plaster to cure and then painters can paint the walls at a later date – once all the work is completed on the Library/EcolgyLab interior.

I have a thing for lichens and mosses. For a curator, of a historic house museum and one who also does stone monument conservation, probably not something you would think but. They are little microcosms of life full or all sorts of tiny things – and a small feast for birds looking for what they hold (insects). I am not here to identify this for you. I am here to have you appreciate its beauty. This large and lovely piece I found at the Coffin School on Winter Street laying on the brick path just before the front portico. To better appreciate it in a photograph, I put it up (temporarily) on one of the marble footings of the Coffin School’s columns. It is a stunner. Maria Mitchell took daily nature walks and was a naturalist as well. Her father, William, led daily nature walks for his students. It highlights the importance of observing things that you also might think do not matter, like this lichen. Next time you are our and about, try and look closely at how beautiful it is and how many chickadees might be clinging to the lichen and moss on a fence or the side of a house as they mine it for goodies!

March 21. {1855} I have held to tears just behind my eyelids for a month, not being able to cry because of the danger of affecting mother and being ready to do so, at every moment. I felt when this year came in, a sinking of the heart, as if it had more duties for me, than I could well go through with. I did not think of the many trials to which in less than three months I must be subjected. Maria started off 1855 with heartache and fear. Several of her close friends died – two of them within four days of one another. Her mother’ Lydia, in failing health went through a very serious bout which caused Maria “great anxiety” as she served as her nurse and caregiver. Happily, Lydia made it through though her health continued to decline over many years. I assume she may have had some form of dementia or possibly even Parkinson’s Disease or perhaps a stroke to start that then kept her in a state of deterioration as years went on. But those things were not as defined, or in some cases, well known or understood then. Lydia would die in 1861, so her family’s care of her, especially Maria’s, must have been some help in keeping her with them. JNLF

I have posted this during Women’s History Month before but because it is March and again Women’s History Month, I think it’s worth repeating. It’s clever and helps to tell an important story in women’s history while giving it a bit of a 21st century twist. It comes via the National Women’s History Project. http://soomopublishing.com/suffrage/ JNLF
