Question: When did the land bridge between Britain and the country compared to a stringed agent while the nation the person paying for Chopin's funeral invited Chopin to was compared to a lion disappear?

full_context: Document 1: Frédéric Chopin: Mozart's Requiem was sung at the funeral; the soloists were the soprano Jeanne-Anais Castellan, the mezzo-soprano Pauline Viardot, the tenor Alexis Dupont, and the bass Luigi Lablache; Chopin's Preludes No. 4 in E minor and No. 6 in B minor were also played. The organist at the funeral was Louis Lefébure-Wély. The funeral procession to Père Lachaise Cemetery, which included Chopin's sister Ludwika, was led by the aged Prince Adam Czartoryski. The pallbearers included Delacroix, Franchomme, and Camille Pleyel. At the graveside, the Funeral March from Chopin's Piano Sonata No. 2 was played, in Reber's instrumentation.
Document 2: Frédéric Chopin: In late summer he was invited by Jane Stirling to visit Scotland, where he stayed at Calder House near Edinburgh and at Johnstone Castle in Renfrewshire, both owned by members of Stirling's family. She clearly had a notion of going beyond mere friendship, and Chopin was obliged to make it clear to her that this could not be so. He wrote at this time to Grzymała "My Scottish ladies are kind, but such bores", and responding to a rumour about his involvement, answered that he was "closer to the grave than the nuptial bed." He gave a public concert in Glasgow on 27 September, and another in Edinburgh, at the Hopetoun Rooms on Queen Street (now Erskine House) on 4 October. In late October 1848, while staying at 10 Warriston Crescent in Edinburgh with the Polish physician Adam Łyszczyński, he wrote out his last will and testament—"a kind of disposition to be made of my stuff in the future, if I should drop dead somewhere", he wrote to Grzymała.
Document 3: Frédéric Chopin: Chopin's tombstone, featuring the muse of music, Euterpe, weeping over a broken lyre, was designed and sculpted by Clésinger. The expenses of the funeral and monument, amounting to 5,000 francs, were covered by Jane Stirling, who also paid for the return of the composer's sister Ludwika to Warsaw. Ludwika took Chopin's heart in an urn, preserved in alcohol, back to Poland in 1850.[n 9] She also took a collection of two hundred letters from Sand to Chopin; after 1851 these were returned to Sand, who seems to have destroyed them.
Document 4: Frédéric Chopin: At the age of 21 he settled in Paris. Thereafter, during the last 18 years of his life, he gave only some 30 public performances, preferring the more intimate atmosphere of the salon. He supported himself by selling his compositions and teaching piano, for which he was in high demand. Chopin formed a friendship with Franz Liszt and was admired by many of his musical contemporaries, including Robert Schumann. In 1835 he obtained French citizenship. After a failed engagement to Maria Wodzińska, from 1837 to 1847 he maintained an often troubled relationship with the French writer George Sand. A brief and unhappy visit to Majorca with Sand in 1838–39 was one of his most productive periods of composition. In his last years, he was financially supported by his admirer Jane Stirling, who also arranged for him to visit Scotland in 1848. Through most of his life, Chopin suffered from poor health. He died in Paris in 1849, probably of tuberculosis.
Document 5: British Isles: The islands enjoy a mild climate and varied soils, giving rise to a diverse pattern of vegetation. Animal and plant life is similar to that of the northwestern European continent. There are however, fewer numbers of species, with Ireland having even less. All native flora and fauna in Ireland is made up of species that migrated from elsewhere in Europe, and Great Britain in particular. The only window when this could have occurred was between the end of the last Ice Age (about 12,000 years ago) and when the land bridge connecting the two islands was flooded by sea (about 8,000 years ago).
Document 6: Frédéric Chopin: At the funeral of the tenor Adolphe Nourrit in Paris in 1839, Chopin made a rare appearance at the organ, playing a transcription of Franz Schubert's lied Die Gestirne. On 26 July 1840 Chopin and Sand were present at the dress rehearsal of Berlioz's Grande symphonie funèbre et triomphale, composed to commemorate the tenth anniversary of the July Revolution. Chopin was reportedly unimpressed with the composition.
Document 7: Coat of arms of the Netherlands: The coat of arms of the Kingdom of the Netherlands was originally adopted in 1815 and later modified in 1907. The arms are a composite of the arms of the former Dutch Republic and the arms of the House of Nassau, it features a checkered shield with a lion grasping a sword in one hand and a bundle of arrows in the other and is the heraldic symbol of the monarch (King Willem-Alexander) and the country. The monarch uses a version of the arms with a mantle () while the government of the Netherlands uses a smaller version without the mantle (cloak) or the pavilion, sometimes only the shield and crown are used (). The components of the coats of arms were regulated by Queen Wilhelmina in a royal decree of 10 July 1907, affirmed by Queen Juliana in a royal decree of 23 April 1980.
Document 8: British Isles: Many larger animals, such as wolf, bear and the European elk are today extinct. However, some species such as red deer are protected. Other small mammals, such as rabbits, foxes, badgers, hares, hedgehogs, and stoats, are very common and the European beaver has been reintroduced in parts of Scotland. Wild boar have also been reintroduced to parts of southern England, following escapes from boar farms and illegal releases. Many rivers contain otters and seals are common on coasts. Over 200 species of bird reside permanently and another 200 migrate. Common types are the common chaffinch, common blackbird, house sparrow and common starling; all small birds. Large birds are declining in number, except for those kept for game such as pheasant, partridge, and red grouse. Fish are abundant in the rivers and lakes, in particular salmon, trout, perch and pike. Sea fish include dogfish, cod, sole, pollock and bass, as well as mussels, crab and oysters along the coast. There are more than 21,000 species of insects.
Document 9: East India Company: The East India Company's arms, granted in 1698, were: "Argent a cross Gules; in the dexter chief quarter an escutcheon of the arms of France and England quarterly, the shield ornamentally and regally crowned Or." The crest was: "A lion rampant guardant Or holding between the forepaws a regal crown proper." The supporters were: "Two lions rampant guardant Or, each supporting a banner erect Argent, charged with a cross Gules." The motto was AUSPICIO REGIS ET SENATUS ANGLIÆ (Latin: By right of the King and the Senate of England).
Document 10: Frédéric Chopin: In April, during the Revolution of 1848 in Paris, he left for London, where he performed at several concerts and at numerous receptions in great houses. This tour was suggested to him by his Scottish pupil Jane Stirling and her elder sister. Stirling also made all the logistical arrangements and provided much of the necessary funding.
Document 11: Europe: This description is simplified. Sub-regions such as the Iberian Peninsula and the Italian Peninsula contain their own complex features, as does mainland Central Europe itself, where the relief contains many plateaus, river valleys and basins that complicate the general trend. Sub-regions like Iceland, Britain, and Ireland are special cases. The former is a land unto itself in the northern ocean which is counted as part of Europe, while the latter are upland areas that were once joined to the mainland until rising sea levels cut them off.
Document 12: Monarchy of the United Kingdom: The Royal coat of arms of the United Kingdom are "Quarterly, I and IV Gules three lions passant guardant in pale Or [for England]; II Or a lion rampant within a double tressure flory-counter-flory Gules [for Scotland]; III Azure a harp Or stringed Argent [for Ireland]". The supporters are the Lion and the Unicorn; the motto is "Dieu et mon droit" (French: "God and my Right"). Surrounding the shield is a representation of a Garter bearing the motto of the Chivalric order of the same name; "Honi soit qui mal y pense". (Old French: "Shame be to him who thinks evil of it"). In Scotland, the monarch uses an alternative form of the arms in which quarters I and IV represent Scotland, II England, and III Ireland. The mottoes are "In Defens" (an abbreviated form of the Scots "In My Defens God Me Defend") and the motto of the Order of the Thistle; "Nemo me impune lacessit". (Latin: "No-one provokes me with impunity"); the supporters are the unicorn and lion, who support both the escutcheon and lances, from which fly the flags of Scotland and England.
Document 13: Elizabeth II: From 21 April 1944 until her accession, Elizabeth's arms consisted of a lozenge bearing the royal coat of arms of the United Kingdom differenced with a label of three points argent, the centre point bearing a Tudor rose and the first and third a cross of St George. Upon her accession, she inherited the various arms her father held as sovereign. The Queen also possesses royal standards and personal flags for use in the United Kingdom, Canada, Australia, New Zealand, Jamaica, Barbados, and elsewhere.
Document 14: British Isles: Few species of reptiles or amphibians are found in Great Britain or Ireland. Only three snakes are native to Great Britain: the common European adder, the grass snake and the smooth snake; none are native to Ireland. In general, Great Britain has slightly more variation and native wild life, with weasels, polecats, wildcats, most shrews, moles, water voles, roe deer and common toads also being absent from Ireland. This pattern is also true for birds and insects. Notable exceptions include the Kerry slug and certain species of wood lice native to Ireland but not Great Britain.
Document 15: Frédéric Chopin: With his health further deteriorating, Chopin desired to have a family member with him. In June 1849 his sister Ludwika came to Paris with her husband and daughter, and in September, supported by a loan from Jane Stirling, he took an apartment at Place Vendôme 12. After 15 October, when his condition took a marked turn for the worse, only a handful of his closest friends remained with him, although Viardot remarked sardonically that "all the grand Parisian ladies considered it de rigueur to faint in his room."
