Decode Oseira – Seal IV

“The Sacred Heart of Oseira” is a photograph of a cloister from the Spanish monastery of Santa María la Real de Oseira. It was taken in 2007 by Paul Preece as part of his “Cloisters” series.


The image is of interest due to the accidental presence of divine symbols hidden in plain view. The term accidental is used in the sense that the symbols were not added to the image in post-production: the symbols are present on the original 5″x4″ black and white negative.

Symbol I – The Heart

The symbol that gives the artwork it’s title is the heart.


If the photograph had been taken either earlier or later in the day or even on a different day or season would the heart shape be as strong as it is? The lower parts of the heart are flanked by the upper ends of the strong light entering the cloister. It is difficult to say whether different light would alter the heart shape sufficiently to make it unrecognisable. What is clear is that cloisters live and breathe light and they can go from a dull and murky gloom to a full-on box of light in seconds. Their medieval builders knew this and could plan the layout of the architecture accordingly to utilise the daily passage of the sun and how it filtered into the cloister and its galleries.

Symbol II – The Circle of Life & Death

The circle has no beginning and no end. It is a classical symbol in art history for the infinite, the divine, the immortal. God.


The circle has no breaks or branches, it is one continuous line in which all is connected. No point on the line is more important than any other. There are many examples of the symbolism of the circle throughout history and across the globe. The symbol of the United Nations is that of 5 concentric circles, the table of King Arthur and his knights was famously round.

I have called it “the circle of life & death” simply because that is what it was named by the first person to recognise it, Luis, a Cistercian monk from the monastery. When I revisited the monastery with a copy of the photograph I had not seen any symbols at all. Luis immediately pointed out both the heart (The Love of God) and the circle (The Circle of Life & Death). What was obvious to Luis was not to me.

It took me a long time, maybe 10 years, before I came to recognise any symbols other than the heart and the circle. Probably because I was not looking closely enough.

Symbol III – The Holy Trinity

In religious art the Holy Trinity has for centuries been represented by various symbols. One of the most common is that of three interlocking circles.


Symbol IV – Hearts

There are more hearts located in the cloister galleries.
