An interesting essay here on 'The Virtue of Architecture':

Of note especially Filarefo's ideal city of Sforzinda - and his portrayal of 'virtue' as a (winged) armed man (Sforza) with Fama/Glory above (his own picture is different to our world card here - but the concept is similar).
Thanks. Looks interesting. For the moment I'm occupied with another project.
