Thomae Smithi Angli De republica Anglorum libri tres : quibus accesserunt chorographica illius descriptio, aliique politici tractatus
A Latin treatise on the English commonwealth by Thomas Smith, with additions by Joannes de Laet, printed in 1630 at Leiden by the Elzevier press for scholars of constitutional law. The picture is a page detail showing a large decorated initial B set in ornate scrollwork beside lines of black-letter Latin type, a plain example of early seventeenth-century book ornament a designer could borrow for letterform and framing ideas.
