March 16, 1885. In February, 1831, I counted seconds for father, who observed the annular eclipse at Nantucket. I was twelve and a half years old. In 1885, fifty-four years later, I counted seconds for a class of students at Vassar; it was the same eclipse, but the sun was only about half-covered. Both days were perfectly clear and cold.
In the 1850s, this eclipse observation was “documented” post-eclipse by Herminia B. Dassel, an artist who had come to the island to paint Abram Quary, the last male Wampanoag on the island. One of the portraits is at the Atheneum, the other at the Nantucket Historical Association. The interesting thing about the Mitchell eclipse double portrait is that it is not Maria posed with her father but instead the youngest Mitchell sister, Kate (Eliza Katherine). Maria refused to sit for the portrait. The artist would take many liberties in her interpretation of the event, the equipment, and Kate’s appearance (she looks like her eighteen year old self, not twelve year old Maria, and is not dressed as a Quaker would be). William Mitchell and the artist were finally able to convince Maria to sit for a portrait. You will find this portrait on our website, the more recognized one of her peering through a telescope and dressed as a Quaker. Maria would become close to the artist, becoming the godmother of the artist’s daughter. Dassel would also paint a portrait of William Mitchell. We have a photograph of the portrait but sadly the portrait was lost within the family.
