paragraph_text: Wearing green and shamrocks
  
  On Saint Patrick's Day, it is customary to wear shamrocks, green clothing or green accessories. Saint Patrick is said to have used the shamrock, a three-leaved plant, to explain the Holy Trinity to the pagan Irish. This story first appears in writing in 1726, though it may be older. In pagan Ireland, three was a significant number and the Irish had many triple deities, which may have aided St Patrick in his evangelisation efforts. Roger Homan writes, "We can perhaps see St Patrick drawing upon the visual concept of the triskele when he uses the shamrock to explain the Trinity". Patricia Monaghan says there is no evidence the shamrock was sacred to the pagan Irish. Jack Santino speculates that it may have represented the regenerative powers of nature, and was recast in a Christian context — icons of Saint Patrick often depict the saint "with a cross in one hand and a sprig of shamrocks in the other".
  
  The first association of the colour green with Ireland is from a legend in the 11th century Lebor Gabála Érenn (The Book of the Taking of Ireland). It tells of Goídel Glas (Goídel the green), the eponymous ancestor of the Gaels and creator of the Goidelic languages (Irish, Scottish Gaelic, Manx). Goídel is bitten by a venomous snake but saved from death by Moses placing his staff on the snakebite, leaving him with a green mark. His descendants settle in Ireland, a land free of snakes. One of the first, Íth, visits Ireland after climbing the Tower of Hercules and being captivated by the sight of a beautiful green island in the distance.
  
  The colour green was further associated with Ireland from the 1640s, when the green harp flag was used by the Irish Catholic Confederation. Later, James Connolly described this flag as representing "the sacred emblem of Ireland's unconquered soul". Green ribbons and shamrocks have been worn on Saint Patrick's Day since at least the 1680s. Since then, the colour green and its association with St Patrick's Day have grown. The Friendly Brothers of St Patrick, an Irish fraternity founded in about 1750, adopted green as its colour. The Order of St Patrick, an Anglo-Irish chivalric order founded in 1783, instead adopted blue as its colour, which led to blue being associated with Saint Patrick. In the 1790s, the colour green was adopted by the United Irishmen. This was a republican organisation—founded mostly by Protestants but with many Catholic members—who launched a rebellion in 1798 against British rule. Ireland was first called "the Emerald Isle" in "When Erin First Rose" (1795), a poem by a co-founder of the United Irishmen, William Drennan, which stresses the historical importance of green to the Irish. The phrase "wearing of the green" comes from a song of the same name about United Irishmen being persecuted for wearing green. The flags of the 1916 Easter Rising featured green, such as the Starry Plough banner and the Proclamation Flag of the Irish Republic. When the Irish Free State was founded in 1922, the government ordered all post boxes be painted green, with the slogan "green paint for a green people"; in 1924, the government introduced a green Irish passport.
  
  The wearing of the 'St Patrick's Day Cross' was also a popular custom in Ireland until the early 20th century. These were a Celtic Christian cross made of paper that was "covered with silk or ribbon of different colours, and a bunch or rosette of green silk in the centre".
