José, Josseph or Joseph Penso de la Vega, best known as Joseph de la Vega (ca.1650, Espejo, Spain — November 13, 1692, Amsterdam, Netherlands), was a successful Jewish merchant, poet, and philanthropist residing in 17th century Amsterdam.
He then e-mailed images to librarians and historians in towns near Córdoba, asking if they recognized the landscape, and received a positive response from a community called Espejo.
Rather than return to the now unfriendly Rio Grande Valley, Espejo decided to return to Mexico via the Pecos River which he called "Rio de Las Vacas" because of the large number of bison the Spaniards encountered during the first six days they followed the river downstream.
He contributed to Black Mirror/Espejo Negro, a book on the works of Pedro Lasch, edited by Lasch, published by Duke University Press.
