Wright met Richard Lumley, second earl of Scarborough, in 1733. Through this contact the Admiralty approved the publication, in 1734, of Wright's Clavis pannautici. In 1742 he published Clavis coelestis, a large engraved diagram of the heavens intended as a teaching aid. In 1750, he published An Original Theory of the Universe, for which he became famous. He concluded that the stars must be arranged in a disc or grindstone, an idea that would later be seen as a precursor to the work of William Herschel.
Wright visited Ireland in 1746. Around this time he was giving tuition to aristocratic ladies on the subjects of mathematics and astronomy. He was also engaged in surveying estates, planning at least 15 gardens and grottoes. He published two volumes of Universal Architecture in 1755 and 1758. He bought the house where he had been born in 1755, re-built it and improved the site over the next few years. He died there in 1786.
