Geraldine Brooks very nearly missed the inspiration for her latest novel, this month's feature book Caleb's Crossing.
The Australian-born writer was poring over a map of significant sites on the island of Martha's Vineyard, off the coast of Cape Cod, when she saw a reference to the first Native American to graduate from Harvard.
Glancing at the map, Brooks read Caleb Cheeshahteaumark's graduation as 1965 and wondered if he was still alive. But a closer look at the date showed that it actually read 1665, a full 300 years earlier.
That snippet of fact set the mind of the historical novelist whirling. How did this young man from the Native American Wampanoag community end up studying at Harvard? What was Harvard like in the 1600s? What became of Caleb after graduation?
I was intrigued by these same questions when I first read about the novel. But because Brooks uncovered very few facts about Caleb's life in her research, I knew not to expect they would be answered in Caleb's Crossing.
