As for engravings, Durer's work was restricted to portraits and illustrations for his treatise. The portraits include Cardinal-Elector Albert of Mainz; Frederick the Wise, elector of Saxony; the humanist scholar Willibald Pirckheimer; Philipp Melanchthon, and Erasmus of Rotterdam. For those of the Cardinal, Melanchthon, and Durer's final major work, a drawn portrait of the Nuremberg patrician Ulrich Starck, Durer depicted the sitters in profile, perhaps reflecting a more mathematical approach. Despite complaining of his lack of a formal classical education, Durer was greatly interested in intellectual matters and learned much from his boyhood friend Willibald Pirckheimer, whom he no doubt consulted on the content of many of his images. He also derived great satisfaction from his friendships and correspondence with Erasmus and other scholars. Durer succeeded in producing two books during his lifetime. "The Four Books on Measurement" were published at Nuremberg in 1525 and was the first book for adults on mathematics in German, as well as being cited later by Galileo and Kepler. The other, a work on city fortifications, was published in 1527. "The Four Books on Human Proportion" were published posthumously, shortly after his death in 1528.

Josie started planning her new garden in the winter. She chose flowers and vegetables that could grow in her area. She looked through the seed magazines. She ordered the tastiest kind of each vegetable and the prettiest kind of each flower. She talked to a friend about her plans. It seemed like the snow would never melt. But Josie didn't have to wait for spring to get started. Six weeks before the last frost, Josie planted seeds indoors. The tiny seedlings pushed up through the soil and began to grow. Finally spring arrived. Each day, Josie moved the seedlings outside for a few hours so they could get used to the cooler temperatures. Josie worked in her garden, digging the soil. She added a special growing mix from the garden store to make the soil better. When everything was ready, she removed the seedlings from their trays and planted them in her garden. The warm sun and rich soil helped her vegetables and flowers grow.

How did Josie get her vegetables to grow so quickly?

Alexander Sergeyevich Pushkin (/'pUSkIn/; Russian: Aleksandr Sergeevich Pushkin, tr. Aleksandr Sergeyevich Pushkin; IPA: [aljI'ksandr sjI'rgjejIvjItc 'puskjIn]; 6 June [O.S. 26 May] 1799 - 10 February [O.S. 29 January] 1837) was a Russian author of the Romantic era who is considered by many to be the greatest Russian poet and the founder of modern Russian literature. Pushkin was born into Russian nobility in Moscow. His matrilineal great grandfather was Abram Gannibal, who was brought over as a slave from what is now Cameroon. Pushkin published his first poem at the age of fifteen, and was widely recognized by the literary establishment by the time of his graduation from the Tsarskoye Selo Lyceum. While under the strict surveillance of the Tsar's political police and unable to publish, Pushkin wrote his most famous play, the drama Boris Godunov. His novel in verse, Eugene Onegin, was serialized between 1825 and 1832. Notoriously touchy about his honour, Pushkin fought as many as twenty-nine duels, and was fatally wounded in such an encounter with Georges-Charles de Heeckeren d'Anthes. Pushkin had accused D'Anthes, a French officer serving with the Chevalier Guard Regiment of attempting to seduce the poet's wife, Natalya Pushkina.
