Mary Dyer ( d.1660) was a Quaker whose doctrine of Inner Light was similar to Hutchinson's salvation by grace received directly from God. At the time, practice of the Quaker religion was not allowed in Massachusetts. She witnessed for religious freedom in Boston three times. Twice she was banished, but the third time she was hanged. Dyer was a friend of Anne Hutchinson and walked out of church beside her following Hutchinson's excommunication. This statue, erected in 1959 from a descendant's bequest, was sculpted by Sylvia Shaw Judson.
