Over my many years now, as a teacher and researcher in the history of the visual arts, many of my studies have not reached completion. However, they contain thought that I still think important and expressed, I have intended, accessibly.  It may be that, though fragmentary to varying degrees, they contain material, critical observation or argument that will be of interest or use to others who study or think upon matter overlapping with what I have addressed. I hope that the pieces that I present here are sufficiently well-labelled that the reader will find selection simple and will reward expectation, that texts will have a brevity, so that a speculative embarkation on the part of the reader won’t be fear of excessive burden.  Eventually, a broad range of topics will be touched on in this blog.  But, at the beginning of the exercise, I shall set forth material on the subject of a prevailing object of my interest –the art-theorist, architect, writer, papal civil servant and moralist, Leon Battista Alberti (1404-72).
