Ritratto di Frà Luca Pacioli (1495). Luca Pacioli (1445–1517) is the central figure in this painting exhibited in the Museo e Gallerie di Capodimonte in Napoli (Italy). The painter is unknown, although some people are convinced the painter is Jacopo de’ Barbari (1440–1515). It shows Pacioli standing behind a table and wearing the habit of a member of the Franciscan order. He draws a construction on a board, the edge of which bears the name Euclides. His left hand rests upon a page of an open book. This book may be his Summa de Arithmetica, Geometria, Proportioni et Proportionalità or a copy of Euclid. Upon the table rest the instruments of a mathematician: a sponge, a protractor, a pen, a case, a piece of chalk, and compasses. In the right corner of the table there is a dodecahedron resting upon a book bearing Pacioli’s initials. An rhombicuboctahedron (a convex solid consisting of 18 squares and 8 triangles) suspends at the left of the painting. The identity of the young man at the right is uncertain, but one commentator recognizes the “eternal student” instructed by Pacioli. Some authors have also mentioned the possibility that the student is Durer.
Pretty medieval manuscript of the day shows the Office of the Dead - appropriate because today is All Souls Day. It is from a stunning early sixteenth century book of hours in the collection of the Getty Museum.
All Souls Day falls on the 2nd of November and is the day that medieval Catholics prayed and did penance to remember the souls of the dead. It is still an important day in the Catholic and Anglican churches.
