Sonnet 77

　　Thy glass will show thee how thy beauties wear，

　　Thy dial how thy precious minutes waste，

　　The vacant leaves thy mind's imprint will bear，

　　And of this book this learning mayst thou taste：

　　The wrinkles which thy glass will truly show

　　Of mouthed graves will give thee memory；

　　Thou by thy dial's shady stealth mayst know

　　Time's thievish progress to eternity；

　　Look what thy memory cannot contain

　　Commit to these waste blanks，and
