Tree of Science

Among the most creative ideas to emerge from the mind of the Catalan philosopher and logician Ramon Llull was the "tree of science". Llull, who was born about 1232, wrote this mature work in Rome between 1295 and 1296. The Tree of Science (Arbre de la ciència, Arbor Scientiae) explores the generality of science, ars magna, for the non-university reader.

Llull's trees are not true networks but simply rely on a teaching analogy that had become popular in the preceding 13th century: the comparison with an organism, in which each science is represented by a tree with roots, trunk, branches, leaves and fruits. It is perhaps not a surprise that the comparison mixes with the idea of Christ's cross as a tree. Here is a drawing on fol 266r:

The roots represent the basic principles of each science; the trunk is the structure; the branches, the genres; the leaves, the species; and the fruits, the individual, his/her acts and his/her finalities (Wikipedia). The 16 trees in the work have been described as an "encyclopaedic grove".

The Vatican Library's copy dates from 1428 and is bound in two volumes. The first has been online for a while, and the second part came online last week and opens with the incipit, In desolatione et fletibus stans Raymundus sub quadam arbore.  The electronic Thorndike and Kibre (eTK) adds that the title first appeared in print at Barcelona in 1482.
