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.
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).
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.
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.

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?
Answer: about 8,000 years ago
