The Book of Hours known as Huntington Library Manuscript HM 1174 is one of my favorites. If you like, you can take a quick look at many of its images here, with thumbnails, brief descriptions and much larger images.
The first twelve images are devoted to the typical medieval
calendar. Here's the description provided by the Huntington Library
catalogue of these pages:
Each month of the
calendar written across an opening; both sides with bracket borders
in the outer margins so as to almost enclose the
opening; in the lower margins, framed by gold columns and arches are, - on
the verso a monthly occupation; and - on the
facing recto, a smaller occupation scene continuing the activity of the
divided by a column from the adjacent zodiac
Here are the twelve, divided up according to season:
The Minneapolis Institute of Arts, owner of a favorite museum website, has joined the Google Art Project. Looking over its 158 offerings there, I spotted the Six Tuscan Poets, 1544, by Giorgio Vasari. One is Dante and another is Petrarch. Who are the other four? According to ArtsConnected, the six are, from left to right: Marsilio Ficino, Cristoforo Landino, Giovanni Bocaccio, Francesco Petrarch, Dante Alighieri, and Cavalcanti.
Vasar is, of course, best known for his "Lives of the Florentine Artists." He was, however, an artist himself and, as we can see from this work, quite a good one.
A human being is a part of the whole, called by us "Universe," a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest, a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us.
Having described the problem, Einstein then continues:
Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security.
