Thomas Rice Lyster was the son of Colonel Anthony Lyster, "a substantial Irish landowner with an aristocratic lineage traceable to the reign of Elizabeth I" (cf. DNB). Lyster appears, in 1838, as a subscriber to Papers on Subjects Connected with the Duties of the Corps of Royal Engineers. The 1842 New Army List shows that he was made a second lieutenant on 18 December 1835, perhaps around the time that he completed the present manuscript. He was promoted to first lieutenant on 20 November 1837, but died while serving in the Royal Engineers Corps in Barbados in February, 1842.
According to the Records of the Royal Military Academy (RRMA), published in 1851, it was common for cadets like Lyster to copy material distributed to them by instructors into blank books, such as the present manuscript. Thus, it is probable that this manuscript was an important piece of Lyster's educational materials. According to the standards of the RMA, as detailed in the RRMA, cadets' books were often gathered by instructors and then shown to the Lietuenant-Governor in charge of the school. Prizes may have been awarded to superior student work. The Records note that there were multiple instructors teaching cadets how to make mechanical and plan drawings, landscape drawings, and how to survey. The curriculum established for the Corps of Royal Engineers, which seems to have been newly designed in 1832 (according to the RRMA), notes that students were expected to be "employed in the practice of surveying, in drawing, or in study, for not less than eight hours per day" (RRMA, 136).
