We have measured solar surface rotation from sunspot drawings made in A.D. 1642-1644 and find probable differences from present-day rates. The 17th century sunspots rotated faster near the equator by 3 or 4%, and the differential rotation between 0 and :t:20 ~ latitude was enhanced by about a factor
