St. Luke, Evangelist, ora pro nobis!
Besides his abilities in physic, he is said to have been very skillful in painting. The Menology of the Emperor Basil, compiled in 980, Nicephorus, Metaphrastes, and other modern Greeks quoted by Gretzer in his dissertation on this subject, speak much of his excelling in this art, and of his leaving many pictures of Christ and the Blessed Virgin. Though neither the antiquity nor the credit of these authors is of great weight, it must be acknowledged, with a very judicious critic, that some curious anecdotes are found in their writings. In this particular, what they tell us is supported by the authority of Theodorus Lector, who lived in 518, and relates that a picture of the Blessed Virgin painted by St. Luke was sent from Jerusalem to the Empress Pulcheria, who placed it in the church of Hodegorum which she built in her honour at Constantinople. Moreover, a very ancient inscription was found in a vault near the Church of St. Mary in via lata in Rome, in which it is said of a picture of the Blessed Virgin Mary discovered there, "One of the seven painted by St. Luke." Three or four such pictures are still in being; the principal is that placed by Paul V in the Barghesian chapel in St. Mary Major.EWTN
