The same year, 1513, Ponce de Leon, an old Spanish soldier in the wars with the Moors, a companion of Columbus in his second voyage, and till now governor of Porto Rico, began exploration to the northward. Leaving Porto Rico with three ships, he landed on the coast of an unknown country, where he thought to find not only infinite gold but also the much-talked-about fountain of perpetual youth. His landing occurred on Easter Sunday, or Pascua Florida, March 27, 1513, and so he named the country Florida. The place was a few miles north of the present town of St. Augustine. Exploring the coast around the southern extremity of the peninsula, he sailed among a group of islands, which he designated the Tortugas. Returning to Porto Rico, he was appointed governor of the new country. He made a second voyage, was attacked by the natives and mortally wounded, and returned to Cuba to die.
Crossing the solar spectrum are hundreds and hundreds of dark lines. These could not at first be explained, because this fact of discriminative absorption was not known. We understand now. The sun's white light comes from the photosphere, but between us and the photosphere there is, as we have seen, another solar envelope of relatively cooler vapours--the reversing layer. Each constituent element in this outer envelope stops its own kind of light, that is, the kind of light made by incandescent atoms of the same element in the photosphere. The "stoppages" register themselves in the solar spectrum as dark lines placed exactly where the corresponding bright lines would have been. The explanation once attained, dark lines became as significant as bright lines. The secret of the sun's composition was out. We have found practically every element in the sun that we know to be in the earth. We have identified an element in the sun before we were able to isolate it on the earth. We have been able even to point to the coolest places on the sun, the centres of sun-spots, where alone the temperature seems to have fallen sufficiently low to allow chemical compounds to form.
Memling (1425?-1495?), one of the greatest of the school, is another man about whose life little is known. He was probably associated with Van der Weyden in some way. His art is founded on the Van Eyck school, and is remarkable for sincerity, purity, and frankness of attitude. As a religious painter, he was perhaps beyond all his contemporaries in tenderness and pathos. In portraiture he was exceedingly strong in characterization, and in his figures very graceful. His flesh painting was excellent, but in textures or landscape work he was not remarkable. His best followers were Van der Meire (1427?-1474?) and Gheeraert David (1450?-1523). The latter was famous for the fine, broad landscapes in the backgrounds of his pictures, said, however, by critics to have been painted by Joachim Patinir. He was realistically horrible in many subjects, and though a close recorder of detail he was much broader than any of his predecessors.
