due to the fact that while in Spain the Gregorian calendar had already
been introduced, the "Old Style", or Julian reckoning, was still used
in England; indeed, it was not totally abandoned until 1752, in the
reign of George II, 170 years after the first use of the Gregorian
reckoning on the Continent. In the seventeenth century the error to be
corrected amounted to ten days, so that Shakespeare's death, under the
New Style, occurred on May 3, while Cervantes died on April 13 of the
Old Style.

In commemoration of the Tercentenary of Shakespeare's death, the
Shakespearean scholar, Miss H.C. Bartlett, prepared for the New York
Public Library an exhibition of Shakespearean books, including all the
early editions of the quartos; the various editions of the folios; the
works of contemporaneous authors whom Shakespeare had consulted; and
also the early works that mention Shakespeare, or cite from his plays
or poems, including Greene's "Groat's Worth of Wit", published in 1592
by Henry Chettle and containing the earliest printed allusion to
Shakespeare under the name of "Shake-scene".

One of the contemporary books containing citations from Shakespeare's
works, shown at the New York Public Library, is "The Woman Hater", by
Francis Beaumont (?1585-1615 or 1616), printed in 1607.[11] The
citation, from _Hamlet_, Act i, sc. 5,[12] is apropos of the
disappearance of a "fish head". It is put into the mouths of two of
the characters, as follows:


_Lazarello_. Speak, I am bound to hear.
_Count_. So art thou to revenge when thou shalt hear.
