The pоem "Sir Pаtrick Spens" is а ____________. Sir Pаtrick Spens The King sits in Dunferline tоun, Drinkin the blude-reid wine 'O whaur will A get a skeely skipper Tae sail this new ship о mine?' O up and spak an eldern knight, Sat at the king's richt knee; 'Sir Patrick Spens is the best sailor That ever sailt the sea.' Our king has written a braid letter And sealed it wi his hand, And sent it to Sir Patrick Spens, Wis walkin on the strand. 'Tae Noroway, to Noroway, Tae Noroway ower the faem; The King's dauchter o Noroway, Tis thou maun bring her hame.' The first word that Sir Partick read Sae loud, loud laucht he; The neist word that Sir Patrick read The tear blindit his ee. 'O wha is this has duin this deed An tauld the king o me, Tae send us out, at this time o year, Tae sail abuin the sea? 'Be it wind, be it weet, be it hail, be it sleet, Our ship maun sail the faem; The King's dauchter o Noroway, Tis we maun fetch her hame.' They hoystit their sails on Monenday morn, Wi aw the speed they may; They hae landit in Noroway Upon a Wodensday. 'Mak ready, mak ready, my merry men aw! Our gude ship sails the morn.' 'Nou eer alack, ma maister dear, I fear a deadly storm.' 'A saw the new muin late yestreen Wi the auld muin in her airm And gif we gang tae sea, maister, A fear we'll cam tae hairm.' They hadnae sailt a league, a league, A league but barely three, When the lift grew dark, an the wind blew loud An gurly grew the sea. The ankers brak, an the topmaist lap, It was sic a deadly storm. An the waves cam ower the broken ship Til aw her sides were torn. 'Go fetch a web o silken claith, Anither o the twine, An wap them into our ship's side, An let nae the sea cam in.' They fetcht a web o the silken claith, Anither O the twine, An they wappp'd them roun that gude ship's side, But still the sea cam in. O laith, laith were our gude Scots lords Tae weet their cork-heelt shuin; But lang or aw the play wis playd They wat their hats abuin. And mony wis the feather bed That flattert on the faem; And mony wis the gude lord's son That never mair cam hame. O lang, lang may the ladies sit, Wi their fans intae their hand, Afore they see Sir Patrick Spens Come sailin tae the strand! And lang, lang may the maidens sit Wi their gowd kames in their hair, A-waitin for their ane dear loes! For them they'll see nae mair. Half-ower, half-ower to Aberdour, Tis fifty fathoms deep; An there lies gude Sir Patrick Spens, Wi the Scots lords at his feet!
