The observatory is only a feeble imitation of that at Djepour; but it has the advantage over the latter of an elevated situation, which dominates an immense plain, while the observatory of Djepour is situated in a plain, and the rising and setting of the stars cannot be seen, except from the top of a masonry gnomon of prodigious height." - [Previous: c14.3](https://indike.org/pramana/ins.science.kaye-1918.c14.3) - [Next: c14.5](https://indike.org/pramana/ins.science.kaye-1918.c14.5) - [Up: c14](https://indike.org/pramana/ins.science.kaye-1918.c14) --- Source: [https://indike.org/pramana/ins.science.kaye-1918.c14.4](https://indike.org/pramana/ins.science.kaye-1918.c14.4) · Pramāṇa
