पाटीगणित (श्रीधराचार्य - प्राचीन संस्कृत टीका एवं प्रो. कृपाशंकर शुक्ल सविस्तार व्याख्या)

xxvi INTRODUCTION
This divergence, which is evidently due to continual
modifications and interpolations made by teachers
engaged in teaching this subject, clearly proves that
this work was very popular and continued to be
used as a text-book for a long time.
The works of Śrîdharâcârya were studied not only by
the Hindus but also by the Jainas, as is evident from the
occurrence of references to Śrîdharâcârya or quotations from
his works in the writings of Abhayadeva Sûri, Siṁhatilaka
Sûri, and Amara Siṁha Yati, who were all Jaina scholars.
Vallabha, who wrote a commentary on the Triśatikâ in the
Telugu language, was also a Jaina.
Appreciation of Śrīdharâcârya.
The works of Śrîdharâcârya, which were so popular,
earned a great name for their author. The following verse,
which is generally cited in appreciation of him both by the
Hindus and the Jainas gives an idea of the unique position
occupied by him as a mathematician :
उत्तरतो सुरनिलयं दक्षिणतो मलयपर्वतं यावत् ।
प्रागपरोदधिमध्ये नो गणकः श्रीधरादन्यः ॥¹
“Up to the abode of the gods (i.e., the Himalayas)
towards the north and up to the Malaya mountain
towards the south and between the eastern and western
oceans, there is no mathematician except Śrîdhara.”
From the Kâvyakalpalatâ-vṛtti² of Amar Siṁha Yati we
learn that Śrîdharâcârya was considered to be so great as a
mathematician that the ideal of a Hindu mathematician was
to be a Śrîdhara.

already seen that the rules for (i) reducing a chain of

referred to above. It is also found to occur in the end of several manu-
scripts of the Triśatikâ, including that containing the commentary by
Vallabha.
