Maps of London

I should be grateful to any of your correspondents who could inform me whether there are any maps of London before that of Aggas? what they are? and where they are to be found? The date of Aggas's map is supposed to be about 1560, and must have been after 1548, as the site of Essex House in the Strand is there called "Paget Place." There is a MS. map by Anthony Van Den Wyngerde in the Sutherland Collection in the Bodleian, the date of which would be about 1559.
