Nobiliario del conde de Barcelos don Pedro, hijo del rey don Dionis de Portugal
A 1646 Madrid genealogy of Portuguese nobility, compiled from the work of Pedro Afonso, Count of Barcelos, and edited by Manuel de Faria e Sousa for a readership of Spanish and Portuguese gentry. Its pages are dense typeset columns of names, dates and marriages, set in running headers, numbered entries and large display capitals such as the 'TIT XXIII' and 'TIT XLVIII' chapter openings. A designer might take the block-like hierarchy of headings, tight tabular columns, and bold initial letters as a model for structured text layout.
