As an expert in the field of fantasy literature, specifically focusing on the works of J.R.R. Tolkien and his legendary universe of Middle-earth, I am well-versed in the intricate details and lore that make up the rich tapestry of this fictional world. When it comes to the age of Gandalf, also known as Mithrandir, one of the most enigmatic and beloved characters in "The Lord of the Rings" and other related works, it's a question that delves into the complex mythology that Tolkien has woven. Gandalf is one of the five Istari, a group of beings known as the Wizards, who were sent to Middle-earth by the Valar, the god-like powers, to aid in the struggle against the dark forces. The Istari were Maiar, spirits who had existed before the creation of the world. Gandalf, originally known as Olorin, was among the wisest of these spirits, and his age is measured in terms of the time before the world began as we know it. The reference material you provided suggests that Gandalf walked in Middle-earth for approximately 2,019 years, maintaining an un-aging appearance of a grey-bearded human in his sixties. This is a simplification of his true age, as it does not account for the time he spent in existence before his mission to Middle-earth. Gandalf, along with Saruman and Sauron, who are also Maiar, have a shared antiquity that predates the physical creation of Middle-earth and the Years of the Lamps, a time when the world was first shaped by the Valar. It's important to note that the concept of age for a Maia, like Gandalf, is not the same as it is for mortal beings. Their existence began in the spiritual realm before the world of matter was formed. When they entered Middle-earth, they did so in the form of an old man to match the lifespan and experience level of the races they were meant to guide and assist. The Istari were sent to Middle-earth during the Third Age, which is the time period in which "The Lord of the Rings" takes place. Gandalf the Grey, as he was known initially, was active for much of this age, and his influence was profound. His age in terms of years lived in Middle-earth is indeed a small fraction of his true age when considering his existence as a Maia. To summarize, Gandalf's age is a complex matter that involves understanding the different planes of existence within Tolkien's universe. His physical presence in Middle-earth spanned two millennia, but his true age as a Maia is far greater, stretching back to the time before the world was made. The age comparison with Saruman and Sauron is also a testament to their shared origins as powerful spirits in the service of the Valar. Now, let's proceed with the translation into Chinese. read more >>

Gandalf walked in Middle-earth for approximately 2,019 years, un-aging and appearing as a grey bearded human of about 60 years old or so. He was around long before Middle-earth was created and before the Years of the Lamps. He, Saruman and Sauron are approximately the same age - give or take.read more >>
