...it's more complicated. Recorde introduced = in the mid-16th century, but it was only in the first half of the 17th century that people started using this sign in printed books (manuscripts are another story). There were both competing symbols for equality on the one hand, and different uses of = on the other hand. For details see the first volume of Cajori's History of Mathematical Notations.
