effect. The only objection to this system was the expense of the double printing;

and this was overcome in 1507 by Erhard Oeglin of Augsburg, who printed both stave and notes simultaneously, entirely superseding Petrucci's method. Schoffer at Mainz did the same in 1511, and so did the Gardano family at Venice from 1536 for about a century and a half. Palestrina's Masses were printed in parts at Rome in 1572, with a coarse but very legible type. And the process used at the present day is pretty nearly the same, only greatly improved in all its details.

In England the first known attempt at Music-printing is in Higden's Policronicon, printed at Westminster in 1495 by Wynken de Worde. The characters (see reduced fac-simile annexed) represent the consonances of Pythagoras. This appears to have been set up piecemeal and not
