Yes, there are several references to the number 19 in the Dark Tower series' books 1-4. The significance of the number 19 is one of the recurring themes in the series and carries great importance for the characters and the overall story arc.
One of the most notable references to the number 19 appears in the first book of the series, The Gunslinger, when the protagonist Roland tells a story about a group of soldiers who went missing after reaching a town with the number 19 in its name. He also mentions that he is nineteen years old when he first sets out on his quest to reach the Dark Tower.
In addition to the direct mention of 19, there are also subtle references throughout the series. For example, in the second book, The Drawing of the Three, Roland encounters a character named Eddie Dean who is addicted to heroin. Eddie's drug dealer calls himself "The Pusher" and is described as wearing a button with the number 19 on it. This reference suggests that the number 19 may be associated with addiction and temptation.
Furthermore, the number 19 appears on the license plate of a car that appears in the third book, The Waste Lands, which is driven by a character who is significant to the story. Additionally, in the fourth book, Wizard and Glass, there is a scene where Roland and his friends pass through a tunnel with 19 doors, each leading to a different dimension.
Overall, the references to the number 19 in the Dark Tower series are deliberate and serve as a recurring motif that adds depth and meaning to the story. The symbolism behind the number remains a mystery to some extent, but it is clear that it holds great significance for the characters and the overarching themes of the series.
