Mondrian cake
The cake pictured below was baked in honor of the great Dutch artist Piet Mondrian, whose abstract art “reached a point where his artistic vocabulary was reduced to simple geometric elements,” to quote from Wikipedia.

For some strange reason, both of the beautiful Roman-centric maps pictured below the fold popped into my Twitter feed less than two hours apart on 4 February 2019. Hat tips to Simon Kuestenmacher (@simongerman600) for the top map, circa 20 A.D., and to Cliff Pickover (@pickover) for the bottom map, circa 43 A.D. Thanks Twitter! Continue reading
