[Q]: Passage: The Catacombs of Rome contain most of the surviving Christian art of the Early Christian period, mainly in the form of frescos and sculpted sarcophagi. They show a Christian iconography emerging, initially from Roman popular decorative art, but later borrowing from official imperial and pagan motifs. Initially, Christians avoided iconic images of religious figures, and sarcophagi were decorated with ornaments, Christian symbols like the Chi Rho monogram and, later, narrative religious scenes. The Early Christians' habit, after the end of their persecution, of building churches (most famously St Peter's, Rome) over the burial places of martyrs who had originally been buried discreetly or in a mass grave perhaps led to the most distinctive feature of Christian funerary art, the church monument, or tomb inside a church. The beliefs of many cultures, including Judaism and Hinduism as well as classical paganism, consider the dead ritually impure and avoid mixing temples and cemeteries (though see above for Moche, and below for Islamic culture).
In the late Middle Ages, influenced by the Black Death and devotional writers, explicit memento mori imagery of death in the forms of skulls or skeletons, or even decomposing corpses overrun with worms in the transi tomb, became common in northern Europe, and may be found in some funerary art, as well as motifs like the Dance of Death and works like the Ars moriendi, or "Art of Dying". It took until the Baroque period for such imagery to become popular in Italy, in works like the tomb of Pope Urban VIII by Bernini (16281647), where a bronze winged skeleton inscribes the Pope's name on a tablet below his enthroned effigy. As cities became more crowded, bones were sometimes recovered after a period, and placed in ossuaries where they might be arranged for artistic effect, as at the Capuchin Crypt in Rome or the Czech Sedlec Ossuary, which has a chandelier made of skulls and bones.
Question: What shows a Christian iconography emerging, initially from Roman popular decorative art?
[A]: surviving Christian art of the Early Christian period.

[Q]: Passage: De Long's party found no immediate sign at their landing-place of any human habitation, and had only a sketchy idea of where they werePetermann's map provided few useful details. On September 19, having buried their non-essential possessions in a mound marked by a tent pole, they set out in search of settlements. Progress was hampered by the poor physical condition of the men, in particular Eriksen, who was badly affected by frostbite. On September 21 they halted at two empty huts, probably part of a hunting camp, where Alexey raised spirits by shooting a deer to replenish their dwindling food stocks. De Long allowed his exhausted party several days' rest before resuming the march.On September 28 the party found a large hut, with signs of recent occupationedible food in the store, and moccasin tracks in the snow. When searches in the locality brought no sign of people, De Long decided to move on. By October 4, Eriksen could not continue; the party halted at another abandoned hut where, on October 6, Eriksen died. On October 9, with the condition of several men worsening, De Long decided to send two of the fittest in the group, Nindemann and Noros, to seek help. Ambler was offered the opportunity to go with them, but felt that his duty as a doctor required him to stay with the main body.For the next week De Long's party struggled on, sometimes making barely a mile a day. Although they jettisoned more of their possessions on the way, De Long insisted on carrying his maps and journals. His entry for October 10 recorded that there was "nothing for supper but a spoonful of glycerine". A few days later Alexey, the group's principal hunter, shot a ptarmigan which provided soup. But Alexey was weakening, and on October 17 he died.On October 20, trapped by the weather and without supplies, the party came to a final halt. Throughout the march De Long had written up his journal each day, but after October 20 his entries became intermittent, largely limited to terse statements of the dying and the dead. He noted the deaths of Kaak and Lee on October 21, Iverson on the 28th, Dressler on the 29th. His last entry, dated October 30, records the deaths of Boyd and Gortz and ends "Mr Collins dying".
Question: What is the last name of the person who entry for October 10 recorded that there was "nothing for supper but a spoonful of glycerine?"?
[A]: De Long.
